Write out your work on a separate sheet of paper - you will be turning this in. It is due IN class at the beginning of class.
You may NOT use your notes for this, NOR may you use the blog or other online resources. Use the equations given. This is a low-stress way to give me a sense of what you know today.
n = c/v
c = 3 x 10^8 m/s
n1 sin (theta 1) = n2 sin (theta 2)
sin (critical angle) = 1/n
1. Consider a rectangular (but 3-d) piece of amber (n = 1.55). Light hits it an angle of 70 degrees (with respect to normal). The block is large enough so that the light can enter and exit without interference. Find the following:
a. a drawing that represents this problem
b. the angle of refraction inside the amber
c. the angle as the light ray leaves the amber
d. the critical angle of amber
e. speed of light inside amber
2. Consider a set of parallel lines hitting a convex lens. Draw this, showing exactly what the light rays do inside the lens and outside the lens (after they leave). Be clear and specific in your drawing.
Part 2 of homework. Play around with this applet (if time allows):
