As for this invention, the incident light the perpendicular line of the surface in the beam and the concave mirror which forms angle (131 and 134) it has, the body (136) it forms the light figure, and/or, the illuminant (130) from light parallel light (137) it regards the system in...
For plane mirrors, virtual images are formed. Light does not actually pass through the virtual image location; it only appears to an observer as though the light was emanating from the virtual image location. The image formed by this concave mirror is a real image. When a real image is for...
SB,19) a man uses a concave mirror for shaving . He keeps his face at a distance of 25 cm from the mirror and gets an image which is 1.4 time enlarged.Find the focal length of the mirror. Solution ocal length, f= ? Object distance, u=-25 cm...
Plane mirrors and convex mirrors always form a virtual image of an object.
Figure 1. Two sets of rays from common points on an object are reflected by a flat mirror into the eye of an observer. The reflected rays seem to originate from behind the mirror, locating the virtual image. Now let us consider the focal length of a mirror—for example, the concave sph...
