Here is the problem I am working on: Sunlight enters a room at an angle of theta = 32° above the horizontal and reflects from a small mirror lying flat on the floor. The reflected light forms a spot on a wall that is d = 1.9 m behind the mirror, as shown in Figure 26-42. If you now place a pencil under the edge of the mirror nearer the wall, tilting it upward by 5.0°, how much higher on the wall (delta y) is the spot? Here is what I have done: delta y = yf - yi = d tan thetaf - d tan thetai = (1.9m)(tan37 - tan32) = 24.45 cm In WebAssign, I submitted both 24.45 cm and 24 cm, but neither was accepted. What am I doing wrong? My instructor said my answer is not close to that in WebAssign.
