Question

please solve this I need a detailed explanation

The radius of curvature of a plano convex lens which has 2 Refractive Index is 20 cm. By applying silver bromide on its surface to change it as a concave mirror, What is the focal length of the formed mirror.​​​

Answer 1

Answer:

10cm

Explanation:

You can measure the radius of curvature (R) of the mirror by measuring the distance between convex miror an

d the screen placed behind the mirror. You can calculate the focal length of the mirror using the equation f = R/2.

f= 20/2

f=10cm.

I hope this helps
