Light travels with a speed of 2×108m/s in crown glass of refractive index 1.5, what is the speed of light in dense flint glass of refractive index 1.8
(1) The speed of light in a transparent medium is 2.4 × 108 m/s. Calculate absolute refractive index of the medium.
(2) The speed of light in water and glass is 2.2 × 108 m/s and 2 × 108 m/s, respectively. What is the refractive index of −
(a) water w.r.t. glass
(b) glass w.r.t. water.
(3) Refractive index of water is 4/3 and speed of light in air is 3×108 m/s. Find speed of light in water.
The velocity of light in a glass block of refractive index 1.5 is:
(Velocity of light in air = 3 x 108 m s-1 )
The speed of light in glass is 1.5 x 108m/s. Then refractive index of glass is
