A single slit diffraction pattern is obtained on a screen using yellow light. If the yellow light is replaced by blue light without making any other changes in the experimental set up, what will happen to the diffraction bands?

Answer :

Diatonic254

The diffraction bands would reduce.

Diffraction is the bending of a wave without any changes to the properties of the wave. During diffraction a wave changes direction of propagation.

Explanation:

The blue light would diffract less than the yellow light because the wavelength of blue light is shorter than that of yellow light in the electromagnetic radiation spectrum. Waves with shorter wavelength diffract less and are easily blocked by obstacles, especially when the obstacle is larger than the wavelength of the wave, while waves with longer wavelengths are able to diffract and pass past obstacles. This is why radio waves of longer wavelengths are ideal in communication over hilly/mountainous places
