Figure below shows a parallel beam of monochromatic light incident on a convex spherical surface, radius of curvature R = 30 cm, which separates glass (refractive index - 1 6) from air. Find the position of the image formed due to refraction of light at this single spherical surface.

Text Solution

Verified by Experts

Given R=30 cm
n=1.6
We know, `(n)/(v)-(1)/(u)=(n-1)/(R)`
`(1.6)/(v)+(1)/(oo)=(1.6-1)/(30)`
`v=(1.6xx30)/(0.6)`
v=80 cm
