Consider the situation shown in figure. Water (μ=4/3) is filled in a beaker up to a height of 10cm. A plane mirror is fixed at a height of 5 cm from the surface of water. Distance of image from the mirror after reflection from it of an object O at the bottom of the beaker is

at which it will be totally internally reflected is the angle of incidence The velocity of light in a medium is half its velocity in air. If ray of light emerges from such a medium into air
