Velocity of light ____cm/sec.

Velocity of light in water is 3/4 times the velocity of light in vacuum. Find the refractive, index of water.

The critical angle of a ray of light incident at the surface of separation of two immscible liquids is 64^(@)48' . If the refractive index of a liquid is 1.4 and velocity of light in vacuum is 3 xx 10^(10) cm * s^(-1) , calculate the probable two values of light in the other liquid.

If the velocity of light in vacuum is 3xx10^(8)ms^(-1) , the time taken (in nanosecond) to travel through a glass plate of thickness 10 cm and refractive index 1.5 is

Fill in the blanks:- Velocity of light in water is ________.

Does velocity of light in vacuum depend on (a) wavelength of light (b) frequency of light ( c ) intensity of light?

A macroscopic dust particle of mass 0.01 mg is. moving with a velocity of 100 cm//sec . Calculate its wave length [h = 6.625 xx 10^-27 erg-sec.] will be wave phenomenon like diffraction be observed for the above particle? Justify your answer

Statement I : The twinkling of star is due to reflection of light. Statement II : The velocity of light changes while going from one medium to the other.
