What is the effect of a comatic aberration on a lens' image?

answer (Click to Show Hidden Text)

The image appears to have a "tail" due to different magnifications along the lens

(also, which part of the rules does this fall under?)

I believe it is under d-vi as coma is typically seen in telecopes.

Correct. Also, I agree with appleshake. The coma appears in telescopes. Be prepared. With such restrictive test rules, you will probably meet an event supervisor who stretches the rules like this. Although, I think the question is justifiable.

Interesting lol

Question:
In the prism below, α is 35° and θ is 19°. The prism has index of refraction 1.45 and is in a vacuum


What is the deviation?

A ray of light traveling through a vacuum strikes medium 1 with an angle of incidence of 43 degrees, and an angle of refraction of 36. Another ray of light traveling through a vacuum strikes medium 2 with an angle of incidence of 87 degrees, and an angle of refraction of 26.

A. Given the index of refraction for a vacuum is 1 find the refractive indices for both mediums.

B. Then find the Brewster angle for the interface of medium 1 and medium 2, where medium 1 is the first medium for light to pass through.

I want a mirror that can give me an image that is upright and has a height that is less than the object's height. What type of mirror do I need and where must the object be placed?

You need a diverging mirror. The object can be placed anywhere in front of the mirror
