Question

An object is placed at a distance of 10 cm from a convex mirror of focal length 15cm. Draw a ray diagram show the formation of the image

Answer 1

Answer:

Explanation:

OBJECT DISTANCE, U = - 10 CM

FOCAL LENGTH, F= + 15 CM

IMAGE DISTANCE ,V=?

WE KNOW, 1/U+1/V=1/F

-1/10+1/V=1/15

1/V= 1/15+1/10

V = 6 CM

FORMED OF THE RIGHT SIDE OF THE MIRROR.

MAGNIFICATION= - (V/U)

MAGNIFICATION=  6/10

MAGNIFICATION = 0.6

SINCE POSITIVE IMAGE IS VIRTUAL [ NOT OBTAINED  ON A SCREEN ]

SINCE MAGNITUDE < 1 DIMINISHED IMAGE IS OBTAINED.

HOPE THIS HELPS.
