(d) A diamond is immersed in such a liquid which has its refractive index with respect to air as greater than the refractive index of water with respect to air. Then the critical angle of diamond-liquid interface as compared to critical angle of diamond -water interface willΒ
Question 12 (Choice 2) (d)
A diamond is immersed in such a liquid which has its refractive index with respect to air as greater than the refractive index of water with respect to air. Then the critical angle of diamond-liquid interface as compared to critical angle of diamond -water interface will
(i) π_1<π_2 (ii) π_1=π_2 (iii) π_1βͺπ_2 (iv)π_1>π_2
Given,
π_ππππ’ππ = π_π€ππ‘ππ
Critical angle of diamond with liquid
πΆβ²=sin^(β1)β‘γπ_ππππ’ππ/π_πππππππ γ
Critical angle of diamond with water
πΆβ²=sin^(β1)β‘γπ_π€ππ‘ππ/π_πππππππ γ
sinβ‘πΆ>sinβ‘πΆβ²
πΆ>πΆβ²
So the correct answer is (iv)
