Rarefraction.
Crest- tallest spot on transverse wave.
Trough- shortest point on transverse wave.
Compression - spot on a compressional wave where the waves are closer together.
Rarefraction - spot on a compressional wave where the waves are farther apart.
Answer:
Frequency of the wave is 3.8 hertz.
Explanation:
It is given that, the sinusoidal wave has following wave equation as :
![y(x,t)=(2.5\ m)sin[(3\ m^{-1})x-(24\ s^{-1})t+\pi/2]](https://tex.z-dn.net/?f=y%28x%2Ct%29%3D%282.5%5C%20m%29sin%5B%283%5C%20m%5E%7B-1%7D%29x-%2824%5C%20s%5E%7B-1%7D%29t%2B%5Cpi%2F2%5D)
The general equation for the sinusoidal wave is :
Where
A is the amplitude
k is the constant
is the angular frequency
is the phase difference
Since, 
or
f = 3.8 Hz
So, the frequency of the wave is 3.8 hertz. Hence, this is the required solution.
Answer
It will stay the same!
Explanation:
If you so happen to move something from left to right, the size of it is not being shrunk or expanded in any type of way, shape, or form.
Answer:C (198 seconds)
Explanation: The cyclist makes the first lap in (180.00 - 6.00) = 174.00 seconds. The average time per lap for all three circuits is (600.00 - 6.00) = 594/3 = 198 seconds.
