Determine the wave speed of a wave that is .85 m from trough to trough and has a frequency of 62 Hz.

i don't know that i agree with that but what's the question ?

not too sure thinking all accelerations are pointed down

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
