A spotlight is on the ground 20 ft away from a wall and a 6 ft tall person is walking towards the wall at a rate of 2.5 ft/sec. How fast is the height of the shadow changing when the person is 8 feet from the wall? (A) -2.0833 B) -0.5433 C) -0.4533 D) -2.0444
A light beam shines through air and then strikes a mirror, making an angle theta = 39.0 degrees with respect to the vertical, as shown. The reflected beam then strikes a pane of glass of thickness h = 1.68 cm, located a distance y= 48.5 cm from the mirror, and then exits the glass pane at the bottom, a horizontal distance x cm away from where it struck the mirror. What is the value of x?

1) What is the speed of light in a glass(n=1.5)? 2) A man 1.80 m tall stands in front of a vertical plane mirror. What is the minimum height of the mirror, if he is to see his whole body? Assume his eyes are 10 cm below the top of his head.
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?

After a long day of driving you take a late-night swim in a motel swimming pool. When you go to your room, you realize that you have lost your room key in the pool. You borrow a powerful flashlight and walk around the pool, shining the light into it. The light shines on the key, which is lying on the bottom of the pool, when the flashlight is held 1.2 m above the water surface and is directed at the surface a horizontal distance of 1.5 m from the edge. If the water here is 4.0 m deep, how far is the key from the edge of the pool? (Given refractive index of water is = 1.33) 1.5 m 1.2 m 4.0 m
