A light bulb is at a depth of D below the surface of water. An opaque disc of radius R is placed on the surface of water just above the bulb. The bulb is not at all seen through the surface of water, then (n = Refractive index of water)

As the position of an object (u) reflected from a concave mirror is varied, the position of the image (v) also varies. By letting the u changes from 0 to + ∞ the graphbetween v versus u will be

When light is incident on a medium at angle i and refracted into a second medium at an angle r, the graph of sin i vs sin r is as shown in the graph. From this, one can conclude that

The graph between the lateral magnification (m) produced by a lens and the distance of the image (v) is given by

The graph shows variation of with v change in u for a mirror. Points plotted above the point P on the curve are for values of v

The graph shows how the magnification m produced by a convex thin lens varies with image distance v. What was the focal length of the used lines

Which of the following show appropriate variation of refractive index μ with wavelength λ?

The graph between u and v for a convex mirror is

For a concave lens, if real image is formed the graph between (u + v) and u or v is as follows
