A container is filled with water `(mu=1.33)` upto a height of 33.25 cm. A concave mirror is placed 15cm above the water level and the image of an object placed at the bottom is formed 25 cm below the water level. Focal length of the mirror is

A container is filled with water (mu=1.33) upto a height of 33.25cm. A convex mirror I s placed 15cm above the water level and image of an object placed at the bottom is formed 25cm below the water level. Focal length of the mirror is

A container is filled with water (mu= 1.33) upto a height of 33.25 cm .a concave miror is placed 15 cm above the water level and the image of an object placed at the bottom is formed 25 cm below the water leverl[Fig.2.90].Find the focal length of the concave mirror.

A container is filled with water (mu = 1.33) up to height of 33.2 cm . A concave mirror is placed 15 cm above the water level. Image of an object placed at the bottom is formed at the same place. The focal length of mirror is :

The real image of an object placed at 60 cm from a concave Mirror is formed at 20 cm. from the mirror. Find the focal length of the mirror.

A tank of height 33.25 cm is completely filled with liquid ( mu = 1.33). An object is placed at the bottom of tank on the axis of concave mirror as shown in the figure. Image of the object is formed 25 cm below the surface of the liquid, then focal length of the mirror is

An object is fixed at the bottom of a vessel and water is filled in the vessel upto a height of 10 cm. A plane mirror is placed at a height of 7 cm from the surface of water in such a way that its reflecting surface faces the water. The distance of the image from the mirror is (Refractive index of water, n = 1.33)
