Question

A thin prism of 6° angle gives a deviation of 3° what is the refractive index of the material of the prism

Answer 1

Answer:

Explanation:

deviation (δ) is given by

δ=(μ−1)A

where μ is refractive index

A is angle of prism.

from given information δ=3

Answer 2

$\huge \underline \pink{Solution:}$

Explanation:

➥ σ = A ( n - 1 )

➥ 3° = 6° ( n - 1 )

➥ 3°/6° = n - 1

➥ 1/2 = n - 1

➥ n = 1/2 + 1

➥ n = 1 + 2/2

➥ n = 3/2

➥ n = 1.50
