A glass slab of thickness 8 cm contains the same number of waves as 10 cm of water, when the same monochromatic light transverses both. If the refractive index of water is 4/3, then the refractive index of glass is

Answer: (A)

Solution

Number of waves = μt/λ₀, so 8μ_g = 10 × 4/3 giving μ_g = 5/3; the
