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?.

Respuesta :

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

What is two - slit interference?

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.

The fringe  width is given by the relation

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.
