Apparent Shift Of An Object Due To Refraction

Deviation Of Ray Due To Refraction

Find the apparent depth and apparent shift of an object placed at the bottom of the vessel containing a glass slap of thickness 10 cm and water of height 50 cm. as shown in the figure.

What is meant by the apparent size of an object ? With a neat and labelled diagram, explain the relation between the apparent size of an object and the angle subtended by the object at the eye.

In Fig. , find the apparent depth of the object seen below surface AB.

The weight of an object is due to

At which angular speed the earth should rotates so that the apparent weight of an object at equator will become zero ?

The apparent depth of an object at the bottom of tank filled with a liquid of refractive index 1.3 is 7.7 cm. what is the actual depth of the liquid in the tank ?
