A beaker is filled with water as shown in figure (a). The bottom surface of the beaker is a concave mirror of large radius of curvature and small aperture. The height of water is h = 40 cm . It is found that when an object is placed 4 cm above the water surface, the image coincides with the object. Now the water level h is reduced to zero but there will still be some water left in the concave part of the mirror as shown in figure (b). The new height of the object h' above the new water surface so that the image again coincides with the object, will be (Refractive index of water = 4//3 )

A plano convex lens has radius of curvature 10 cm. Its focal length is 80 cm under water. Calculate the refractive index of the material of the lens, given refractive index of water is 4//3 .
