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
For example, an experiment similar to this one could be how pressure could affect the time it takes for an Alka-Seltzer tablet to dissolve. Using A flask and rubber stoppers, you can compare the amount of time it takes for and Alka-Seltzer tablet to dissolve in regular room temperature water and room temperature water in a flak but with a rubber stopper stopping the air flow into the flask. This is related to the experiment performed above because the increase in pressure from the rubber stopper stopping the air flow in and out of the flask may affect the time it would take for the Alka-Seltzer tablet to dissolve. Another example of an experiment related to the one performed above is how the amount of water used to dissolve an Alka-Seltzer tablet effects the time it takes for one to dissolve. This also relates to the experiment performed above because it also affects how fast the rate of reaction is.
The experiment used a light of a single color, or monochromatic light, and two closely spaced slits or pinholes. He realized that the bright fringes of light resulted from light waves from both holes arriving crest to crest, creating a constructive interference. He also realized that the dark areas resulted from light waves coming from trough to crest, creating a destructive interference. The interference fringes made were straight lines. This interference experiment demonstrated the wave nature of light idea generated by Huygens 200 years earlier.
My experiment is elephant toothpaste were foam shoots out of a container or glass. I chose this experiment because I thought it would be fun to see foam shoot out of a bottle. You get to mix curtain substances together to make elephant toothpaste. I thought if I get a small bottle then the most foam should be produced.
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.
8) Explain how each experiment type (question 7) differs from the
We were asked to correctly communicate these findings as we tested each of the substances she had encountered with both water and hexane. In experiment number three, The Relationship Between the Volume of a Gas and the Temperature, we where given a list of materials and asked to come up with our own procedure, which we did using zip lock bags filled with air, and submerged fully in a measured amount of water in order to find the volume, and then the change in volume when the temperature of the water was increased. In the fourth experiment we were asked to find the temperature of heated water, based on the cold and warm water. The experiment also required that each section be preformed several times in order to ensure accuracy, and also asked that the experimental responsibilities be split up between lab partners, each doing a section of the testing. This gave us an opportunity to work together with our fellow lab partners, with no one person doing the bulk of the work.
In "Passage 1: Sound is All around Us, Sound is Energy" Jason Torres claims that sound is a form of waves that vibrate in one directions called longitudinal waves. "The distance between two adjacent compressions, two adjacent rabout the longitudinal arefactions, or a single compression and rarefaction combined is a wavelength of a sound wave. " This is Jason Torres ' definition of Longitudinal Waves. The wave measures the sound and pitch. This pitch and sound can differ due to the extent of energy/waves released.
Strength through burning As Thomas Jefferson, founding father of the United States of America and the main author of the Declaration of Independence, once said, “Experience hath shewn, that even under the best forms of government those entrusted with power have, in time, and by slow operations, prevented it into tyranny.” He is saying that someone who receives too much power will eventually turn this power into something bad. There are examples of this happening in both Fahrenheit 451 and The Wave. Both of these novels had an abundance of power gave to people, which made the group or world turn bad. Starting with The Wave, where a teacher, Ben Ross, turned his whole school upside down for a teaching experience; it all started
Students don't exactly know what was happening, they just found it interesting so they agreed to do the experiment. Laurie thought Mr. ross was taking the experiment too long and she disagreed with what he was doing. The wave was a class experiment, the class showed what the Germans were like but, the students didn't know it was related to
The following examples of the split beam test will do just that. One observes photons acting as waves. They act as waves in every known example.
“Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers” ( Megan Forbes, 1). Odysseus has obtained Poseidon’s wrath, and number one rule is to not
The mechanical vibrations transmitted through a medium; solid, liquid or a gas generates a sound wave. The sound is an energy, which deflects the particles of a medium in the same direction, and itself travel as a longitudinal waveform with areas of compression and rarefactions. The image generated by ultrasound is essentially based on similar principle by means of a machine, which includes an ultrasound transducer and a screen. The transducer contains a piezoelectric crystal made up of lead zirconite, which generates an ultrasound beam on applying an electrical current to the transducer. These signals travel through a medium in the body and after striking with various tissues, return back to the transducer.
The main strength of conducting this experiment is that is shows the behavior exactly as it occurs in the real world.
This experiment has to be carried out carefully
