Question

prove that :
Refractive index=real deal /apparent deapth​

Answer 1

Answer:

Consider a ray of light incident normally along OA. It passes straight along OAA'. This ray gets refracted and passes along BC. On producing this ray BC backwards, it appears to come from the point I, and hence, AI represents the apparent depth, which is less than the real depth AO.
