Question

nothing prism of 4 degree angle gives a deviation of 2.4 degree what is the value of refractive index of material prism​

Answer 1

Explanation:

deviation=angle of prism(n-1)

2.4=4(n-1)

0.6=n-1

n=1.6

Answer 2

The refractive index of material is 1.6.

Explanation:

Given that,

Angle of prism, A = 4 degrees

Angle of deviation, $\delta =2.4^{\circ}$

We need to find the refractive index of material. The expression for angle of deviation of prism is given by :

$\delta=A(\mu -1)$

$\mu$ is the refractive index of material

So,

$\mu=\dfrac{\delta }{A}+1$

$\mu=\dfrac{2.4}{4}+1$

$\mu=1.6$

So, the refractive index of material is 1.6. Hence, this is the required solution.
