Calculate the deviation produced by a pr...

Calculate the deviation produced by a prism of angle `6^@`, given refractive index of the material of the prism is `1.644`.

Text Solution

Verified by Experts

`delta = ? A = 6^@ , mu = 1.644`
As `delta = (mu - 1) A :. delta = (1.644 - 1) 6 = 0.644 xx 6 = 3.864^@`.
