Question

A prism with refractive angle of 60°,gives angle of minimum deviation 53° 51° and 52° for blue red and yellow light respectively what is a dispersive power of the material of prism?​

Answer 1

Dear student,

◆ Answer -

Dispersive power = 0.0385

◆ Explanation -

# Given -

A = 60°

δb = 53°

δr = 51°

δy = 52°

# Solution -

Dispersive power of prism material is calculated by -

Dispersive power = (δb - δr) / δy

Dispersive power = (53 - 51) / 52

Dispersive power = 2 / 52

Dispersive power = 0.0385

Therefore, dispersive power of prism material is 0.0385 .

Best luck dear. Hope this helps you...
