Problem 25.1.01 A light ray strikes a plane mirror lying flat on a horizontal floor, making an angle of incidence of O; = 64.2º. After reflecting from the mirror, the ray makes a spot on a vertical wall. The wall is a horizontal distance d = 1.08 m from the point of reflection, as shown. How high from the floor is the spot on the wall? (Neglect the thickness of the mirror.)

Sunlight enters a room at an angle of 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 2.0 m behind the mirror, as shown in the figure(Figure 1) . 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 (?y) is the spot? ?y=_________cm

A student stands d0= 2.5 m in front of a floor-to-ceiling mirror. Her eyes are he= 1.6 m above the floor and she hold a flashlight at a distance hf =.85 m above the floor. -calculate the angle theta, in degrees, that the flashlight makes with respect to the floor if the light is reflected into her eyes.

A mirror hangs 1.75 m above the floor on a vertical wall. A ray of sunlight, reflected off the mirror, forms a spot on the floor 1.14 m from the wall. Later in the day, the spot has moved to a point 2.50 m from the wall. (a) What is the change in the angle of elevation of the Sun, between the two observations? ° (b) What time of day were these observations made? morning afternoon

Deep in the physics and astronomy basement storeroom, you find a very large concave spherical mirror from an old telescope. The mirror is 2 m across, and has a radius of curvature of 14.0 m. Because this is just a small piece of such a large sphere, the angle of incidence for on-axis rays will always be below 5°, minimizing spherical aberration You try out the mirror for use as a full-length wall mirror.
