Water floats on a liquid called "carbon tetrachloride." The two liquids do not mix. A light ray passing from water into carbon tetrachloride has an incident angle of 45.0° and an angle of refraction of 40.1°. If the index of refraction of water is 1.33, what is the index of refraction of carbon tetrachloride?

Refractive index is defined as the ratio of speed of light in the vacuume and in the medium.The index of refraction of carbon tetrachloride is 1.26.

Refractive index:

It is defined as the ratio of speed of light in the vacuume and in the medium.

where

c -speed of light in vacuum

v - phase velocity of light in the medium.

It can also be calculated by the angle of refration,

Where,

Sin i - angle of incidence = 45.0

sin r - angle of  refraction = 40.1

Put the values in the formula,

Thereforew, the index of refraction of carbon tetrachloride is 1.26.

1.26

Explanation:

= 1.26

true

explanation:

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
