Explain magnification of mirror and lens​

Answer»

Answer:

The mirror formula

1f=1v+1u

Where

f

is the focal length of the mirror,

u

is the DISTANCE of the object from the mirror and

V

is the distance the image is formed from the mirror.

m=−vu

The size of an object’s image is larger (or smaller) than the object itself by its magnification,

M

. The level of magnification is proportional to the ratio of

v

and

u

. An image that is double the size of the object WOULD have magnification

M=2

.

R=2f

The radius of curvature of a mirror is twice its focal length.

Example 1

In the SITUATION illustrated below, the object is SET up .5 m away from a converging mirror. If the focal length of the lens is .2 m, determine a) the location of the real image, and b) the magnification of the image.
