Both waves are traveling at the same speed through the same medium.
Which of the following choices most accurately compares the amplitude and frequency of the two waves?
The green wave has a greater amplitude because the distance from crest to crest is greater than the red wave. The re
greater frequency because its wavelength is smaller than the wavelength of the green wave, but their speeds are the s

The red wave has the same amplitude because its height is the same as the height of the green wave. The red wave h
frequency because its wavelength is smaller than the wavelength of the green wave, but their speeds are the same.
The red wave has the same amplitude because its height is the same as the height of the green wave. The red wave h
frequency because its wavelength is smaller than the wavelength of the green wave, but their speeds are the same.

Question 10
Which of the following choices best describes the behavior of light as it moves from air to glass?
All of the light waves interfere destructively as they enter the glass canceling each other so that no waves exit the glas
Some of the light waves bounce off the glass and diffract at an equal angle. Some of the light waves are reflected as th
move through the glass at a new angle.
Some of the light waves bounce off the glass and reflect at an equal angle, but in a new direction. Some of the light wa
