Question

The apparent depth of a pond is 9 m. what is the real depth if refractive index of water with respect to air is 4/3?​

Answer 1

so ans will be 12 m by using the formula

Answer 2

Answer:

12m

Explanation:

A.D = 9m                                                                                                                                              

 n   = 4/3

n  =  R.D/ A.D

4/3  =  R.D/9

36/3 = R.D

12m =R.D
