When light passes through an object unchanged scientists call that process
Answers
The process is "transmission" of light. The object is "transparent".
When light passes directly through an object unchanged, that object is called transparent. Hope that helped =)

A wave with a period of 0.008 second has a frequency of
Answers
The frequency of a wave is the reciprocal of its period.
A period of 0.008 sec means a frequency of
1 / 0.008 sec = 125 per sec . (125 Hz)
A wave with a period of 0.008 second has a frequency of
1 /.008 = 125 Hz
In a compressional wave the denser the medium is at the compressions the smaller is amplitude?
Answers
Wellll, let me think about that ...
I don't think I'd agree that you can characterize the amplitude of a wave according to the density at only one point in it. After all ... a tiny wave in steel would be much denser at a compression than a huge wave in air would be.
The amplitude of any wave is described as the difference between a peak and the resting value. Or even better ... half of the difference between a maximum and a minimum.
So if you're looking at a longitudinal wave, like sound, I'd say if you want to describe its amplitude, then you have to look at the density at two points ... either the difference between the compression and the resting densities, or the difference between the greatest compression and the greatest rarefaction.
