Adiffraction grating with 750 slits per mm is illuminated by light which gives a first-order diffraction angle of 34.0 ? .

The wavelength of the light is about 7.46 × 10⁻⁷ m

Let's recall diffraction grating formula as follows:

where:

d = distance between the slits ( m )

θ = diffraction angle ( radian )

n = order number

λ = wavelength of light ( m )

Let's now tackle the problem!
