1. What is the physics behind the light amplification of optical
amplifiers? What are the required conditions to make the
amplification happen?
2. Describe what happens below, at, and above the lasing
threshold of a laser in terms of its output power, population
inversion, and gain coefficient.
a) What is the equation of motion that governs the physics
behind sound production in your speaker? Discuss what each term in
this equation of motion relates to in your speaker.
consider the conceptual physics behind the visual
process. explain how the curves of the cornea and the lens relate
to the angle of light waves projection.
describe some of the changes or problems in the eye
structure that can cause a problem with vision.
describe some of these problems and the way they alter
or block like ways for example, cataracts obstruct light waves,
thereby causing problems with vision.
describe the role of photoreceptors and their location
in the eye....
Explain in two to three paragraphs the physics behind center of
mass (or center of gravity) and static equilibrium. Type this up in
your own words and supply an equations or pictures that
might be useful to your explanations. (Remember to site your source
if you use a picture you found on the internet.) (25
points)
Explain, in detail, the physics behind why the magnet
slows its descent through the tube (it does not touch the sides).
In your discussion be sure to explain why the magnet doesn't come
to a stop in the tube and why it does not speed up. Your response
should include at least 3 paragraphs to show your mastery of the
material.
Using words, explain the laws of physics behind this in a
paragraph. Don't just write equations with few
words.

The Horo was used by the Ancient Japanese to deflect arrows from
enemies. Explain how such silk could stop the arrows. The video
itself explains it little but please expand on that more and use
equations/formulas (like perhaps one for KE) to aid the
explanation.
Write down Maxwell’s equations in differential and integral form
and explain the physics behind each one of them. Modify one of them
to account for the existence of magnetic monopoles.
