Question

an object is placed at a distance of 15cm from a convex mirror and image is formed at a distance of 5cm from the mirror.calculate the radius of curvature of the mirror​

Answer 1

$\bf\large\underline\red{TO \:FIND}$

□Radius of curvature of mirror.

$\large\purple{SoLUtION}$

Given,

●Object Distance = 15cm

●Focal length = 5 cm

》So, From mirror Formula

=》1/v + 1/u = 1/f

=》1/v = 1/f - 1/u = 1/5 - (1/-15)

=》1/5 + 1/15

=》3 + 1 /15

=》4/15

$\red{=》 V = 15/4 = 3.75( Virtual Image)}$

Answer 2

Answer:

3.75 is right answer friend
