Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. ... Refraction not only affects visible light rays, but all electromagnetic radiation, although in varying degrees.
So in short, the answer is D.

Answer:
<h2>32m/s^2</h2>
Explanation:
We want to find the acceleration based on the given data
Given
distance s=400m
time t= 5s
u= 0m/s since it started from rest
We apply the following expression
s=ut+1/2at^2
substituting we have
400=0*5+1/2*a(5)^2
400=25a/2
cross multiply
25a=400*2
25a=800
divide both sides by 25 we have
a=800/25
a=32m/s^2
The acceleration is 32m/s^2
The atoms of a molecule can vibrate in many waysthese are
called the normal modes of vibration. The normal modes have different excitation
energies so the Raman spectrum will consist of more than one line. The number
of normal modes is easily deduced; if the number of nuclei in the molecule is
N, then the total number of degrees of freedom (i.e., the number of coordinates
required to specify the positions of all of the nuclei) is 3N. Of these, three
account for translation of the molecule as a whole and three more for its
rotation. So the third is 314 nm
Answer:
v2=0.79 m/s
Explanation:
equation of continuity: V1A1=V2A2
A=(pi)r^2
A1=(pi)(0.55cm)^2
A2=(pi)(1.17cm)^2
convert cm2->m2
A1= 0.95cm2=
A2= 4.3cm2=
(3.57 m/s)(0.000095 m^2)=(x m/s)(0.00043 m^2)
v2=0.79 m/s
hope this helped
