Answer:
D.
Explanation:
Specifically, Special Relativity showed us that space and time are not independent of one another but can be mixed into each other and therefore must be considered as the same object, which we shall denote as space-time. The consequences of space/time mixing are: time dilation. and length contraction.
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:
b. a lens does not focus all colors of light to the same place.
Explanation:
Chromatic aberration is a defect of a lens. In this defect, the lens is unable to focus the different wavelengths of the light on a single focal point. It is also known as chromatic distortion and color fringing. It is caused by the dispersion of light while passing through a lens. As a result, the image might become blurred and different colors are observed around its edges. It can be corrected by the use of a combination of converging and diverging lenses.
Hence, the correct option will be:
<u>b. a lens does not focus all colors of light to the same place.</u>
