Answer: 2
Explanation: The answer to this problem is 2 as—seeing as it’s a mirror— the light won’t go through the mirror. This means that answer choice 4 is wrong. Answer choice 1 is also wrong as the mirror is tilted in such a way as the light will have to go up. This leaves 3 and 2. However, after careful observation, one can eliminate answer choice 3 as the angle of the mirror would have to be a perfect 45° degree angle if the light were to go straight up. This leaves answer choice 2.
