Question

calculate the index of refraction of a liquid from the following into glass: (a) reading from the bottom of an empty beaker:11.324 cm (b)Reading for the bottom of the beaker ,when partially filled with the liquid:11.802 cm (c)Reading for the upper level of the liquid in the beaker:12.895 cmplease explain clearly? ​

Answer 1

• Index of refraction of a liquid from the following into glass is 1.437.
• We can solve this question by using the concept of Real depth and apparent depth.

According to the given data-

Real depth = 12.895- 11.324 = 1.571

Apparent depth = 12.895 - 11.802 = 1.093

And we know that refractive index is the ratio of real depth to apparent depth. So,

RI = 1.571/1.093 = 1.437
