Answer
given,
wavelength (λ) = 650 nm
angle = 5°
using bragg's law
d = 7.46 x 10⁻⁴ cm
number of slits per centimeter
=
b) wavelength of two rays 650 nm and 420 nm
d = 2 x 10⁻6 m
we now,
for 650 nm
θ = 40.54°
for 450 nm
θ = 24.83°
now, difference
|θ_{650} -θ_{420}| =40.54°-24.83°
|θ_{650} -θ_{420}| =19.71°
