Answer 1

Answer:

PHYSICS

Light from a point source in air falls on a convex spherical glass surface ( refractive index = 1.5, radius of curvature = 20 cm). The distance of light source from the glass surface is 100 cm. At what position is the image formed ?

ANSWER

Given,

Refractive index, μ=1.5

Radius of curvature, R=20cm

Object distance, u=100cm

Image distance, v=?

We know

vμ2−uμ1=Rμ2−μ1

μ2=1.5

μ1=1

⇒  v1.5+1001=201.5−1

⇒ v1.5=200.5−1001

⇒ v1.5=2003

⇒ v=3200
