The speed of light changes when it goes from ethyl alcohol (nea = 1.389) to carbon tetrachloride (nct = 1.436). What is the ratio vct vea of the speeds?

The ratio of the velocity of carbon tetra chloride and ethyl alcohol is 0.96.

Explanation:

Given that,

Refractive index of ethyl alcohol n= 1.389

Refractive index of carbon tetra chloride n'= 1.436

We need to calculate the ratio of the velocity of carbon tetra chloride and ethyl alcohol

Using formula of velocity

Where, n= refractive index of ethyl alcohol

n'=refractive index of carbon tetra chloride

Put the value into the formula

Hence, The ratio of the velocity of carbon tetra chloride and ethyl alcohol is 0.96.

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8
