Answer:
Explanation:
a) C/V = μ₁/μ₂
where C is speed of light in air
V is speed of light in medium
μ₁ is refractive index of air
μ₂ is refractive index of medium
B) refractive index of ice is (μ₂)= 1.31
refractive index of air is (μ₁) = 1
C/V =μ₁/μ₂
V= C × μ₂/μ₁
= 3 x 10⁸ × 1.31 / 1
= 3.98 x 10⁸m/s
