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) in the light from the two slits at an angle of 28.0 ∘ from the centerline?

∅=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

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
