Question

a mark at the bottom of a liquid appears to rise by 0.1m.the depth of the liquid is 1m.The refractive index of the liquid is

Answer 1

Answer:

The refractive index of the liquid is 10/9 or 1.11.

Explanation:

The refractive index of a liquid can be determined using the following formula:

Refractive index = Real depth/ Apparent depth

The real depth is given as 1m and the mark appears to rise by 0.1m.

Hence the apparent depth is 1-0.1 = 0.9

Therefore, refractive index of the liquid = 1/0.9 = 10/9 or 1.11.
