Sunlight is shown filtering through clouds.What wave phenomenon is responsible for the sunlight shown in this diagram?
A
diffraction, because light is bent around the cloudsB
refraction, because the light bends through the cloudsC
absorption, because the sunlight is absorbed by the cloudsD
transmission, because the sunlight travels through the clouds22

Rohit is trying to tune an instrument. He strikes a tuning fork and then plays a note that almost matches it. Rohit hears the volume of the two waves beating, which sounds like "wah-wah-wah-wah."
A
The two waves produced have different speeds.B
The two waves produced have different amplitudes.C
The two waves produced have different wavelengths.D
The two waves produced have different frequencies.23
Consider this image of a wave.
A
A graph with time in second on the x axis from 0 to 8 and amplitude on the y axis from 2 to 2. The wave starts at the origin and the trough goes up to .8, back down through .75 s and all the way down to 2 before going back up to 2 on the other side of the x axis. It is a repeated pattern with on trough and 3 crests with different amplitude.
B
A graph with time in second on the x axis from 0 to 8 and amplitude on the y axis from 2 to 2. The wave starts at the origin and the trough goes down to 2, back up through 1 s and all the way up to .7 before going back down to .2 on the other side of the x axis. It is a repeated pattern with on trough and 3 crests with different amplitude.
C
A graph with time in second on the x axis from 0 to 8 and amplitude on the y axis from 2 to 2. The wave starts at the origin and the trough goes down to .6, back up through 1s and all the way up to .6 before going back down to .4 on the other side of the x axis. It is a repeated pattern with on trough and 3 crests with different amplitude.
D
A graph with time in second on the x axis from 0 to 8 and amplitude on the y axis from 2 to 2. The wave starts at the origin and the trough goes down to 2, back up through 1s and all the way up to .7 before going back down to .2 on the other side of the x axis. Then back up to .3 on the other side of the x axis. The pattern repeats itself but flipped on the x axis
