It can be used to turn the line of sight (LOS) through an angle or to reverse the image. (2) When two faces of a prism form a sharp angle, and light enters one of these faces and goes out through the other, the prism will bend the light. You can use a prism to bend (deviate) the line of sight. -Attitude of an object produced by two plane mirrors placed at right angles. -Refraction 3-6 in a prism. Some wedges used in fire control and optical alignment instruments appear to be disks or plates of glass with parallel surfaces.

From it. As shown in figure 4-10, they converge to a single point. A light ray that passes along the optical axis through a lens does not bend because it strikes the surfaces of the lens at the normal. Study figure 4-10 carefully. The central ray passes through the optical center of the lens and, even though it is not on the optical axis, does not deviate. Any ray of light passing through the optical center of a lens will actually be offset, but the deviation is so slight it is ignored. View B of figure 4-10 shows how three rays of light from object F are refracted to reproduce that point o n the image d .
