A dance hall is built without pillars and with a horizontal ceiling 7.20 m above the floor. A mirror is fastened flat against one section of the ceiling. Following an earthquake, the mirror is in place and unbroken. An engineer makes a quick check of whether the ceiling is sagging by directing a vertical beam of laser light up at the mirror and observing its reflection on the floor. (a) Show that if the mirror has rotated to make an angle φ with the horizontal, the normal to the mirror makes an angle φ with the vertical. (b) Show that the reflected laser light makes an angle 2φ with the vertical. (c) Assume the reflected laser light makes a spot on the floor 1.40 cm away from the point vertically below the laser. Find the angle φ.
A dance hall is built without pillars and with a horizontal ceiling 7.5 m above the floor. A mirror is fastened flat against one section of the ceiling. Following an earthquake, the mirror is in place and unbroken. An engineer makes a quick check of whether the ceiling is sagging by directing a vertical beam of laser light up at the mirror and observing its reflection on the floor. The reflected laser light makes a spot on the floor 1.6 cm away from the point vertically below the laser showing that the mirror has rotated by angle Φ with respect to the horizon. determine the angle Φ. (Give your answer in decimal with three digits after the decimal point using "degree" as unit.)
Hint: if the mirror rotates by Φ, by how much does the normal to its surface rotate?

Each color of light can carry a separate signal, letting you squeeze more information into your beam. This, of course, leaves you with the problem of how to separate the colors back out once your beam gets to where its going. One way to do this involves total internal reflection.The index of refraction of glass isn't fixed; it's actually a function of frequency. Specifically, the index of the glass n and the angular frequency ω of the light are related by the equation below. Since different colors of light see different indices of refraction, different colors of light will see different critical angles.Suppose we have a beam with green light (frequency ω=3.7e+15 rad/s and red light (frequency ω=2.9e+15 rad/s traveling through this glass.
