In the figure shown, S is a point monochromatic light source of frequency 
. M is a concave mirror of radius of curvature 20 cm and L is a thin converging lens of focal length 3.75 cm. AB is the principal axis of M and L
Light reflected from the mirror and refracted from the lens in succession reaches the screen. An interference pattern is obtained on the screen by this arrangement.
If the lens is replaced by another converging lens of focal length

Statement-1 : A beam of white light enters the curved surface of a semicircular piece of glass along the normal. The incoming beam is moved clockwise (so that the angle 
increases), such that the beam always enters along the normal to the curved side. Just before the refracted beam disappears, it becomes predominantly red.
Statement-2 : The index of refraction for light at the red end of the visible spectrum is more than at the violet end.
