## Homework Statement

SINGLE SLIT

Why does the intensity at maxima decrease further away from the central maxima in a single slit diffraction.

DOUBLE SLIT

Slit width:

Why is the intensity of a double slit interference pattern the same at each maxima. (constructive interference)

When the slit width is negligible

BUT NOT

when the slit width is not negligible.

2. Homework Equations

2. Homework Equations

λ/b=sinθ

Intensity propoportional to Amplitude^2

## The Attempt at a Solution

Could someone please explain using simple vocabulary/ terminology and examples/analogies as I sometimes get confused by very experienced physicists who assume I know what they're talking about. :) :)
