![]() This gives the relation between the diffraction and frequency as they are inversely related. This gives the diffraction of the wave with a certain frequency of the incident wave. If the angle θ is very small then, sinθ~θ, then the equation will be Where 1.22 is the constant d is the diameter of the aperture and θ is the angle between the incident and diffracted wave. If we have considered the aperture as a circular aperture, the equation can be modified as Replacing the λ in the above equation we get Rearranging the terms, we get frequency as The wavelength can be given in terms of frequency as Where θ is the angle between the incident and diffracted wave. The amount of diffraction can be given by the equation, ![]() Image to describe the relation between frequency and diffraction Let us suppose that a light wave of wavelength λ is passed through a slit of width d and the light wave s travels in a straight line to give the diffraction fringes. ![]() This dependency can be expressed by providing the relation between the frequency and diffraction as given below. Though the frequency of the wave and diffracted wave remains the same before and after the diffraction occurs, diffraction always depends on the frequency. The edge of the object is used as the focal point and generates the new wave front whose frequency will remain the same, but the intensity is reduced.
