i am not able to get the concept of appernt depth can you please help?

Dear Student

 

When a wave passes from one medium to another at an angle other than 90°, its speed changes and this leads to change in the direction of the wave (k.a. refraction). 

 

Apparent depth is the Depth that a transparent material such as water or glass appears to have when viewed from above. This is less than its real depth because of the refraction that takes place when light passes into a less dense medium. The ratio of the real depth to the apparent depth of a transparent material is equal to its refractive index. 

 

Hope that satisfies your query.
