A dust particle is inside a sphere of refractive index `4/3.` If the dust particle is `10.0 cm` from the wall of the `15.0 cm` radius bowl, where does it appear to an observer outside the bowl.

In a thin spherical fish bowl of radius 10 cm filled with water of refractive index (4//3) , there is a small fish at a distance 4 cm from the centre C as shown in Figure. Where will the fish appear to be, if seen from (a) E and (b) F (neglect the thickness of glass)?

A fish bowl of diameter 20 cm is filled with a liquid of refractive index 1.4. A letter O is written on the outer surface of the bowl. Determine the position of the image of the word formed when observed through the bowl from the opposite side.

A sphere made of transparent material of refractive index ( mu =3/2 )and of radius 50 cm has a small air bubble 10 cm below the surface. The apparent depth of the bubble if viewed from outside normally is
