Suppose i create a two-slit interference pattern using light with some wavelength lambda and slits with some separation d. If i

were to increase lambda, what would happen to the interference pattern on the wall?.

If we increase the wavelength (λ), fringe width will increase and the interference pattern on the wall will spread out.

<h3>What is two - slit interference?</h3>

The double or two-slit interference is a demonstration that light and matter can display characteristics of both classically defined waves and particles.

It also displays the fundamentally probabilistic nature of quantum mechanical phenomena.

During a two-slit interference experiment, a beam of light is aimed at a barrier with two vertical slits.

<h3>The fringe width is given by the relation</h3>

fringe width = λ L / D

where;

λ is wavelength of light used,
L is distance of wall from the source of light and
D is slit separation.

Thus, if we increase the wavelength (λ), fringe width will increase and the interference pattern on the wall will spread out.
