A ray of light from an object you want to look at strikes a mirror so that the light ray makes a 32 degree angle relative to the normal line (a line perpendicular to the surface of the mirror at the point where the ray strikes the mirror). If you want to see the object in the mirror, what angle does your line of sight need to make relative to the normal line? Give your answer as the number of degrees.
Suppose you have a converging lens with a focal length of 65 cm. You hold this lens 120 cm away from a candle. How far behind the lens should you place a notecard if you want to form a clear image of the candle, on the card? Give your answer as the number of centimeters.
Suppose you have a diverging lens with a focal length of - 25 cm. You look through this lens at a sleeping squirrel, and notice that it forms a virtual image of the squirrel with di = - 18 cm.
How far away from the lens is the squirrel? Give your answer as the number of centimeters (a positive number).
