Answer:
I would say C
Explanation:
A is a steep or about 45° angle while B appears to be a straight down angle of 0°. So if you take that into account, if you are subtracting A and B, it would be around in between. It will probably not be backwards because neither is facing to the left except the answer choices so B is wrong (the answer B).
R is even steeper than before, and if you are subtracting, it would probably be C.
Answer:
a) Red: 1.34
Violet: 1.40
b) Red: 
Violet: 
Explanation:
a) We should use Snell's law to find the index of refraction:
with n1 the index of refraction of air, n2 the index of refraction of the glass, θi the angle of the incident ray respects the normal an θt the angle between the refracted ray an the normal. It's common to approximate n1=1
solving n2 for red light:
solving n2 for violet light:
b) Index of refraction on a medium is defined as the ratio between the velocity of electromagnetic waves on vacuum (velocity of light c) and the velocity in medium (v):
solving v for red:
solving v for violet

Hey, unfortunately it’s impossible for me to draw one for you here, but you should be able to draw it yourself pretty easily!
Answer:
An atom is built with a combination of three distinct particles: electrons, protons, and neutrons. Each atom has a center nucleus, where the protons and neutrons are densely packed together. Surrounding the nucleus are a group of orbiting electrons. And here is a picture that may assist your further :
