A light ray leaves point A in the figure, reflects from the mirror, and reaches point B.
A light ray leaves point A in Figure 1, reflects from the mirror, and reaches point B. How far below the top edge does the ray strike the mirror? What if the distance from point B to the mirror was reduced by 5 cm?
Homework Answers
The incident and reflected light rays will form two right angled triangles as shownFrom the laws of reflection,the angle of incidence = the angle of reflectionx / 10 cm = (10 cm - x) / 15 cm15 x = 100 - 10x25x = 100x = 4 cmTherefore the light ray will strike the mirror at 9 cm below the top edge

A monochromatic light ray enters a glass sphere of radius 5 cm from air as shown in the figure. The incident ray is parallel to the diameter AOB with a separation of h = 4 cm. After entering the glass sphere, the ray crosses the diameter AOB at a certain point between center O and point B.mainly ask (d) and (e)(d) If incident light is unpolarized, is the reflected light at point P perfectly polarized? If not, find another separation...

A plane mirror and a concave mirror (f = 7.90 cm) are facing each other and are separated by a distance of 18.0 cm. An object is placed between the mirrors and is 9.0 cm from each mirror. Consider the light from the object that reflects first from the plane mirror and then from the concave mirror. Draw the ray diagram. What is the distance of the image (di) produced by the concave mirror?

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.)
