Question

a thin prism deviates an incident ray by 3.2 degrees . if the refractive index of the prism is 2.6 then the angle of prism is​

Answer 1

Answer:

Solution.,.................

Angle of prism is 0.5°

Answer 2

Answer:

The angle of prism is 2°

Explanation:

Given that,

• Thin prism deviates an incident ray by 3.2°
• Refractive index (n) = 2.6
• Angle of prism = A

Th find angle of prism we use below formula

Angle of deviation= (n-1) x Angle of prism

where,n is refractive index of prism

Angle of deviation = (2.6-1) x A

3.2 = 1.6 x A

A = 3.2/1.6

= 32/16

= 8/4

= 2

Angle of prism= 2

Hence, the angle of prism of a given prism is found to be 2 degrees
