- A person is standing a distance d = 1.35 m away from a mirror, which is m = 0.870 m above the ground, as shown in Figure 1. Light hits their foot, reflects off of the mirror, and enters their eye (this is how they see the reflection of their foot!). How tall are they? (Measure their height h from the ground to their eye, and don't worry about the small distance from their eye to the top of their head, which we do not have enough information to determine).Can you help me with the wrong. Please? Thank you.Two plane mirrors make an angle α = 54.0◦ between them. A ray of light incident on one of the mirrors is reflected and hits the second mirror. Find the angle β between the ray incident on the first mirror and the ray reflected off of the second mirror. (a) 36.0◦ (b) 72.0◦ (c) 54.0◦ (d) 24.0◦ (e) None of the above.
