1. How does the brightness of the refracted ray change when the incident angle (from glass to air) changes from less than critical angle to greater than critical angle?

a. brighter

b. dimmer

c. unchanged

d. dimmer and then disappear

2. Trying to picture an electroscope you made in the lab, on rubbing an rubber rod with fur, the electrons from the fur get transferred to the rubber rod. While holding the rubber rod near the electroscope (not touching the top paper clip), the foil leaves separate. At the same time, someone rubs a Styrofoam cup on a piece of cloth and also brings it to the electroscope, the leaves close a bit. What is the type of charge the Styrofoam cup carrying?

A. positive

b. negative

c. cannot decide

3. What would be the correct description of how an image in a plane mirror compares to the original object?

a.

The image is reflected left to right

b.

The image is reflected front to back

c.

The image is reflected both front to back and left to right

d.

The sense of the image changes depending on the angle of incidence

e.

It depends on the original object

4. If the distance between the object and the screen is 1meter, a thin lens is put in between and moving, when the lens is 30 cm away from the object, a clear image is formed on the screen. How much is the focal length of this thin lens?

a. 0.048 m

b. 21 cm

c. 0.019 m

d. 52.5

When reaching a boundary between two media, an incident ray is partially reflected and partially refracted. The ray is travelling from media 1 to media 2. The indexes of refraction for the two media are n1 and n2, respectively. At what angle of incidence is the reflected ray perpendicular to the refracted ray? Express your answer in terms of the variables n1 and n2.
