A diver looking up through water `(mu=4/3)` sees the outside world contained in a circular area on the surface of water. If the diver's eyes are `sqrt7m` below the surface of water, then calculate the area of the circle.

A diver looking up through the water sees the outside world contained in a circular horizon. The refractive index of water is (4)/(3) , and the diver's eyes are 15 cm below the surface of 3 water. Then the radius of the circle is:

A fish looking up through the water sees the outside world contained in a circular horizon. If the refractive index of water is 4//3 and the fish is 12cm below the surface, the radius of this circle in cm is

A fish looking up through the water sees the outside world contained in a circular horizon. If the refractive index of water is (4)/(3) and the fish is 12 cm below the surface, the radius of this circle is cm is

A fist looking from within water sees the outside world through a circular horizon. If the fish sqrt(7) cm below the surface of water, what will be the radius of the circular horizon

A solid floats in water with 3//4 of its volume below the surface of water. Calculate the density of the solid.

A diver at a depth of 12 m in water (mu=4 //3) sees the sky in a cone of semi-vertical angle

Will a diver experience greater pressure 10 m below the surface of the water or 20 m below the surface ?

A fish in water sees an object which is 24cm above the surface of water. The height of the object above the surface of water that will appear to the flash is (mu=4//3)
