Solution

The correct option is A $2 H$
From the figure, It is clear that due to similarity in triangles the length of the screen that will receive reflected light from the mirror is $C D = 2 H$ .

Q. In the diagram shown below, a point source O is placed vertically below the center of a circular plane mirror. The light rays starting from the source are reflected from the mirror such that a circular area A on the ground receives light. Now, a glass slab is placed between the mirror and the source O. What will the magnitude of the new area on the ground receiving light? Assume the width of the slab to be very large.

A concave mirror of radius of curvature 10 cm is cut into two equal parts, slightly separated and placed in front of a monochromatic line source S of wavelength 2000 $^A$ as shown in figure.
