2 Amplitude is a measure of what in a wave? Amplitude measures the amount of energy in a wave.
3 What determines the color of a light wave? Frequency and wavelength
4 What is the space called between compressions in a wave? Rarefaction
5 Describe reflection. Give an example of reflection. Reflection is when a wave bounces off a surface.Use any example from our labs in class.
6 Describe refraction. Give an example of refraction. Refraction is when a wave bends when it pass through a different medium.The wave travels at different speeds through the different mediums.Use any example from our labs in class.
7 Describe diffraction. Give an example of diffraction. Diffraction is when a wave bends around a barrier.Use any example from our labs in class.
8 Describe and give an example of a mechanical wave. A mechanical wave is one that needs a medium through which to travel.Sound, earthquake
9 Describe and give an example of a transverse wave. A transverse wave travels in up and down motions.It can be mechanical or electromagnetic.Light, water
10 Describe and give an example of an electromagnetic wave. A electromagnetic wave does not require a medium to travel.All electromagnetic waves are transverse.Light, UV, x-ray
11 Describe and give an example of a compressional wave. A wave that moves back and forth in the direction that it’s traveling.Has compressions and rarefaction.Sound
12 By what is the pitch of a sound measured? Frequency
13 Describe why hearing an explosion in space during a movie is not realistic. Since space has no air, sound cannot travel.
14 If space is a vacuum, how does light travel to Earth from the Sun? Since light is a type of electromagnetic wave, it does not require a medium through which to travel.
15 How is the amplitude different in dim light and bright light? The bright light has more energy which means it has a higher amplitude.Dim light has less energy because it has a lower amplitude.
16 How is the wavelength different in a sound of 100 Hz compared to 500 Hz? The wave of 100 Hz will have a lower pitch.A lower pitch (100 Hz) will have the longer wavelength.
