Answer:
∅=2021rad
Explanation:
Coherent light with wavelength 540 nm passes through narrow slits with a separation of 0.370 mm . At a distance from the slits which is large compared to their separation, what is the phase difference (in radians) i the light from the two slits at an angle of 28.0 ∘ from the centerline?
A wave is a disturbance which travels through a medium, it transfers energy without a permanent displacement of the medium itself. this is an example of light wave
using the formula below
∅=
the phase difference is given from the above
d= distance/separation of slits .00037m
=wavelength
540*10^-9m
=angle of two slits 28.0 ∘
∅=(
∅=2021rad
there are large bright fringes from the centre line
