REFLECTION OF LIGHT

A plane mirror rotating at an angular velocity of 3 radian/s reflects a light beam. The angular velocity of the reflected beam is -

Monochromatic light of wavelength 589nm is incident from air on a water surface. Given, refractive index of water is 1.33. Which of the following statement(s) is/are correct? I. Frequency of reflected light and refracted light are same. II. Wavelength of reflected light is more than that of refracted light. III. Speed of reflected light is equal to that of refracted light. IV. Intensity of reflected light is always more than that of refracted light.

A coverging beam of light is incident on the concave mirror. Then the reflected light :

In total internal reflection, the light travels from

How many internal reflections of light take place in the formation of primary rainbow ?

Does sound follow the same laws of reflection as light does ? Explain.

The colours seen in the reflected white light from a thin oil film are due to

After reflection, the light rays from a point object at the focus of a concave mirror,
