Question

an object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm find the position and nature of the image​

Answer 1

Explanation:

(u) object distance= -10cm

(f) focal length= 15cm

(v) image distance= ?

1/u +1/v = 1/f

1/v= 1/15 + 1/10

1/v = 2+3/30

1/ v = 1/6

v= 6cm

Nature:- Virtual and errect

Size:- Diminished image

Answer 2

Answer:

GIVEN,

U=10 CM

F= 15 CM

V=?

N=?

MIRROR FORMULA,

1 + 1 = 1

V U F

1 + (- 1 ) = 1

V 10 15

1 - 1 = 1

V 10 15

1 = 1 + 1

V 15 10

1 = 2+3

V 30

1 = 5

V 30

30=5V (CROSS MULTIPLICATION )

30 = V

5

6=V

V=6 CM

THE IMAGE IS FORMED 6 CM BEHIND THE MIRROR, VIRTUAL IMAGE IS FORMED.

I HOPE IT HELPS YOU. ..........☺
