A fish is a little away below the surface of a lake. If the critical angle is `49^(@)` , then the fish could see things above the water surface withing an angular range of `theta^(@)` where

The length of a vertical pole at the surface of a lake of water (mu=4/3) is 24 cm. Then to an under-water fish just below the water surface the tip of the pole appeard to be

A small fish 0.4 m below the surface of a lake is viewed through a simple converging ens of focal length 3m. The lens is kept at 0.2 m above the water surface such that fish lies on the optical axis of the lens. The image of the fish seen by observer will be at (mu_("water")=4/3)

A small fish 0.4 m below the surface of a lake is viewed through a simple converging lens of focal length 3 m.the lens is kep at 0.2 m above the water surface such that the fish lies on the optical axis of the lens. Find the image of the fish seen by the observed. (mu_(water)=(4)/(3))

A small fish, 0.4 m below the surface of a lake, is viewed through a simple converging lens of focal length 3m. The lens is kept at 0.2 m above the water surface such that the fish lies on the optical axis of the lens. Find the image of the fish seen by the observer. Refractive index of the water is 4//3 .
