Sunlight enters a room at an angle of 30.0° 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 2.50 m behind the mirror (Figure 28-53). You place a notebook under the edge of the
mirror nearest to the wall, tilting it upward by 4.00°. How much higher on the wall (Ah) is the spot?
