Question

a meter scale is placed along the axis of convex mirror of focal length 25cm.its nearer and being at a distance of 50cm. calculate the size of image formed​

Answer 1

The mirrors formula:

1/ f = 1/u + 1/v

Now :

v = 50 cm

f = 25 cm

1 / 25 = 1 / 50 + 1 / u

1 / u = 1 / 25 - 1/ 50

1 / u = 1 / 50

u = 50 cm

Magnification :

Image distance / object distance

50 / 50 = 1

Size of image :

1 meter × 1 = 1 meter

= 1 meter
