In a swimming pool, a person is viewing outside objects by keeping an eye at a depth h inside water. If the critical angle for water is ‘ `theta_(c)`’, then the value of the diameter of the circle of view for outside objects will be

If we see the outside objects by keeping an eye at a depth h inside water of refractive index u, then the value of RADIUS of circle of view for outside objects will be

For an eye kept at a depth h inside water is refractive index mu , and viewed outside, the radius of circle through which the outer objects can be seen will be

For an eye kept at a depth h inside water is refractive index mu , and viewed outside, the radius of circle through which the outer objects can be seen will be

A man standing on the bottom. The depth o fthe swimming pool looks at a stone lying on the bootom. The depth of the swimming pool is equal to h . At what distance from the surafce of water is the image of the stone formed if the line of vision makes an angle theta with the normal to the surface?

An object lies 100cm inside water. It is viewed form air nearly normallly. Find the apparent depth of the object.

An air masked eye placed inside water refractive index, mu sees the outside world. The vertex angle of the cone in which the eye will see the outside world is

A man standing in a swimming pool looks at a stone lying at the bottom. The depth of the swimming pool is h. At what distance from the surface of water is the image of the stone formed -
