Question

A object is placed at a distance of 12cm from a convex mirror of radius of curvature 12cm. the position and nature of the image a)4cm real b)4cm virtual c)2cm real d)2cm virtual

Answer 1

Hola mate! Here is your answer:

Given:

u= -12 cm

R= 12 cm

f = R/2 = 6 cm

Convex mirror

Solution:

Using mirror formula

$\frac{1}{f} = \frac{1}{v} + \frac{1}{u}$

$\frac{1}{6} = \frac{1}{v} - \frac{1}{12}$

$\frac{1}{v} = \frac{1}{6} + \frac{1}{12}$

$v = 4cm$

Here v is positive so Image is Virtual and inverted

So option (b) is correct
