A ray of light travelling inside a rectangular glass block of refractive index root 2 is incident on the glass-air surface at an angle of incidence of 45^o. The refractive index of air is 1. The ray will The mean distance of sun from the earth is 1.5×10^8 km. The time taken by light to [...]

When a ray is refracted from one medium into another, the wavelength changes from 6000 Å to 4000 Å. The critical angle for a ray from the second medium will be the wavelength changes from 6000 Å to 4000 Å. The critical angle for a ray from the second medium will be When a ray [...]

The speed of light in medium A is 2.0×10^8 m/sec and that in medium B is 2.4×10^8 m/sec. The critical angle of incidence for light tending to go from medium A to medium B is The speed of light in medium A is 2.0×10^8 m/sec and that in medium B is 2.4×10^8 m/sec. The critical [...]

The apparent depth of water in cylindrical water tank of diameter 2Rcm is reducing at the rate of x cm/min when water is being drained out at a constant rate. The amount of water drained in c.c. per minute is (n1= refractive index of air, n2= refractive index of water ) The mean distance of [...]
