Number 3.
When you have two parallel wire and the charges are moving, they create a magnetic field around the wire (right-hand rule, thumb points in the direction of current).
If you want the math, here ya go:
F: magnetic force on the wire, L: length of the wire I: current in one wire I': current in other wire r: distance of the wire.
As we can see, two wires that has current through it will generate a force on each other.

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°
