Light and sound are things that essentially almost every human being has access to to the experience. Light and sound have been observed since the 17th century and there is still even more to discover even today. Light has given us the opportunity to see around us and given advancements including the solar panels. Sound has also given us an opportunity to listen to noises around us like instead of always reading books now people can listen to them with Audiobooks, and people can also have speakers that can help with the intensity of the sound. Sound and light are combined in some cases similar a phone or a computer to give the light needed to see the screen and the sound to hear music and videos. Sound and light are diverse in numerous methods. …show more content…

First of all, what type of wave is light and sound? Light and sound are not the same types of wave. There are 2 types of waves and light is a transverse wave while sound is a longitudinal wave. Source D states, “Longitudinal waves are waves whose direction of vibration is the same as their direction of travel…. Transverse wave is a moving wave that consists of oscillations perpendicular to the direction of the energy transfer.” Suchlike proves that longitudinal and transverse are divergent types of waves. The author Chris Woodford hereto in the article, “ Sound waves are compression waves. They’re also called longitudinal waves…” (Source B pg. 2). Indeed, it proves that sound waves are longitudinal waves. Source A states, “ An electromagnetic wave is a transverse wave that involves the transfer of electric and magnetic energy” (69). Thus, as the text shows that light is transverse waves. Now it is time to see how sound and light …show more content…

Sound can reflect while light can refract, diffract and interfere as well, including reflecting Source C reads, “Light waves behave in 4 interesting and useful ways that we describe as reflection, refraction, diffraction, and interference” (2). As demonstrated, the article says that light can act or behave in 4 multifariously ways. The author states, “ What you hear is, of course, sound reflection, better known as an echo….” (Source B, 2) The base of the data tells that sound can be reflected but cannot be refracted, diffracted, or interfere. Sound and light also differ in how the wave travels. Light travels or acts similar to a wave or particle while sound travels with a medium.“ Like other mechanical waves, sound waves carry energy through a medium without moving the particles of the medium along” (Source A pg. 34) From cited corroboration, it shows that sound travels with a medium. From source A its allures, “It has many properties of waves, but can also act as though it is a stream of particles” (pg. 70). It tells that light can be a wave or a particle. Light and sound are heterogeneous and are also shown in what speed these waves travel at.
Speed is contrary to all types of mediums, and are unlike between sound and light. Sound travels slower than light. From source B the writer states, “The speed of sound in air (at sea level) is about 1120 km or 340 meters per second.” Such as told the speed of sound is around 1120

The three most important properties of a wave are the wavelength, the amplitude, and the frequency. The wavelength is the distance from one point on a wave to the next identical point on the next wave. The amplitude is the distance from a waves rest position to either the crest or trough of the wave. The frequency is a rate which represents the amount of times a wave repeats

This also causes for many different frequencies. The waves of an incoherent light are rampant and out of phase causing them to interfere with one another. On the other hand, a beam of light with the same frequency, phase, and direction is called a coherent light. In this form of light, there is no interference of waves within the beam, and only a beam of coherent light will not spread and diffuse.

Wave properties: Frequency: How many waves go past a point in one second; measured in hertz (Hz). The higher the frequency, the more energy in the wave. 1 Ask the children to play 'verbal tennis' in partners on words that describe sounds (eg loud, quiet, vibration, pitch). One child says one word related to sound, then their partner says another and so on. 2 Ask the children what things make sounds.

Throughout Canada, increasing use is being made of award winning Echo Sound Barriers to counteract noise pollution. As companies become aware of the advantages of the range of noise reduction solutions available from the Echo Barrier company, the impact of noise on the environment in Canada is reducing. This can only be an advantage to the health and welfare of the nation. Unacceptable levels of sound can come from many sources. Construction and building work, demolition sites, generators, airports and railways and even children playing in the garden can make life unbearable for those who live or work in close proximity.

Max Moore Mrs.Carey Language Arts Per.2 10 April 2024 Rogue Waves And Tsunamis Two big waves, rogue waves and tsunamis, both are very dangerous, and both carry water with lots of force. Tsunamis and rogue waves both do damage in the same way, they can destroy oil rigs, and ships. They may seem the same at first, but they are actually very different. Rogue waves are found deep in the ocean and are made from wind. First, rogue waves are found far out at sea, then they stay in the middle of the ocean.

Jordan Brown Mrs. Carey Language arts, period 4 10 April 2024 Rogue waves and tsunamis Did you know that a rogue wave is two times the size of a normal wave and tsunamis because they have several waves. Rogue waves are a single wave that is taller and stronger than a normal wave because the winds and tsunamis are 50 to 100 ft tall! Rogue waves and tsunamis have similarities in locations but are different in the way they are formed. First, usually rogue waves are in deep water and are in the middle of the ocean. In the article it says, “The formation of deepwater rogue waves is a semi-regular phenomenon of the coast of South Africa, where the agulhas current intersects with opposing trade winds but can also occur in the Atlantic Ocean and the

Different sounds are produced by different material, each creating a unique set of sounds. Percussion instruments include the drums, cymbals, triangles, chimes, timpani, bells, and xylophone. String The sound of string instruments comes from then strings vibrating the air around it. The strings may be plucked, bowed, or struck making them vibrate. There a many different types of string instruments such as the violin, cello, harp, and dulcimer.

Sound is embodied in the black body whether it be in everyday conversation, intimate exchanges with a loved one, heart wrenching calls, or music rendered from the soul. Sound is essential to living beings as both a primary and secondary sense used to interact with the world. Sound enables communication. Communication creates community. Community leads to emotional connections and understanding.

The rate at which acoustic waves travel depend on eruption size. As acoustic waves hit the ground, they become ground waves “that shake a seismometer much like earthquake waves do.” Though scientists have observed and disregarded the transition of acoustic waves into ground waves, David Fee, a seismologist at the University of Alaska Fairbanks, decided to study acoustic waves using seismic data from the Veniaminof and Pavlof volcanoes. The article stated how Fee and his team adjusted their data knowing acoustic waves traveled ten times slower than seismic waves. They extracted acoustic waves from seismic data.

A: Snell’s law allows us to work out the index of refraction of light through an object. We can use this and insert into a formulae of “n=c/v. We know that the speed of light is about 300,000 kilometres per second so if we add this into the formulae as well as the index of refraction we can work out the speed of light travelling through the

As light travels through different materials, it scatters off of the molecules in the material and slows down. Nothing ever travels faster than c in vacuum, however, for different mediums, this is not the case. In materials such as water, light will slow down more than electrons will. Thus an electron in water can travel faster than light in water. The amount by which light slows in a given material is described by the index of refraction, or in other words, n.
