Question

A 4cm long object is placed at a distance of 20 am from a concave mirror.find position ,nature and size of image formed?

Answer 1

u = -4 cm (object distance)

f = - 1 cm

v = ?

By mirror formula,

1 = 1 ± 1

f. v. u

1 = 1 + 1

-1. v. -4

= 1 - 0.25

v

1 = -1 +0.25

v

= -0.75

v = 1.

-0.75

= - 1.33cm

Thus, the position of an image is 1.33 cm.

Thus, it will be formed between focus and centre of curvature.

thus, the nature of image is real, inverted and diminished.
