Question

Write the formula for refractive index of the prism and explain the terms in it?
​

Answer 1

Answer:

n=cv n = c v . Explanation: The refractive index of any material is always n>1 , since light is fastest in vacuum, that is, c>v .

Answer 2

The formula for the refractive index of the prism is :

• The Refractive index of a prism is the ratio of the speed of light in one medium to the speed of light in the next medium.
• Due to this changes in the velocity occur when entered from one medium to another.
• The formula of the refractive index of prism =
• $n \: = \frac{ \frac{sin(a + d)}{2} }{ \frac{sin \: a}{2} }$
• Here, n is the refractive index, a is the angle of the prism, while d is the minimum deviation.
