Question

An object at a distance of 15 cm from a convex mirror and image is formed at a distance of 5 cm from the mirror find the radius of curvature of mirror?

Answer 1

$\huge\underline\mathfrak\purple{Answer}$

$\frac{1}{f} = \frac{1}{v} + \frac{1}{u} \\ \\ = \frac{1}{5} - \frac{1}{15} \\ \\ = \frac{3 - 1}{15} \\ \\ f \: = \frac{15}{2} cm$

Radius of curvature = 2 x f

= 15 cm

Thanks!
