Answer
As we know,
Given,
A = 60°
So, substituting the values in the formula above we get,
Hence, the angle of incidence is equal to 48°.

A ray of light incident at an angle of incidence 48° on a prism of refracting angle 60° suffers minimum deviation. Calculate the angle of minimum deviation. [ Hint — δmin = 2i - A ]
An object when placed in a denser medium and is viewed from a rarer medium appears to be at a lesser depth than real death. This is because of :
- reflection
- refraction
- dispersion
- diffraction
Refractive index of a liquid can be found using :
- μ = real depth x apparent depth
- μ = apparent depth/real depth
- μ = real depth/apparent depth
- none of the above
