Question

Find the angle of deviation suffered by the light ray shown in figure for following two conditions The refractive index for the prism material is \( \mu=3 / 2 \) 

(i) When the prism is placed in air \( (\mu=1) \) 

(ii) When the prism is placed in water \( (\mu=4 / 3) \)

Answer 1

s =(\(\mu\)_R -1) A

s = \((\cfrac{\frac{3}{2}}{1}-1)\times3\)

s = 1.5°

s = \((\cfrac{\frac{3}{2}}{\frac{4}{3}}-1)\times3\)

s = \((\frac{9}{8}-1)\times3\)

s = 3°/8
