The angle of diffraction of the blue light that passed through a slit of a diffraction grating is 63.5⁰.

Angle of diffraction

The angle of diffraction of the blue light that passed through a slit of a diffraction grating is calculated as follows;

mλ = dsinθ

sin θ = mλ/d

sin θ = (1 x 425)/475

sin θ = 0.8947

θ = sin⁻¹(0.8947)

θ = 63.5⁰

Thus, the angle of diffraction of the blue light that passed through a slit of a diffraction grating is 63.5⁰.
