![]() ![]() Diffraction gratings work because different wavelengths of light will constructively interfere at different angles. A diffraction grating can be a series of closely-spaced slits or a mirror with a series of small grooves. ![]() Uses of diffraction ĭiffraction can be used to separate different wavelengths of light using a diffraction grating. The strongest examples of diffraction occur in waves where the wavelength is similar to the size of the object causing diffraction. These patterns of interference rely on the size of the diffracting object and the size of the wave. When interference is destructive, the intensity will decrease, sometimes to a point where it is completely destroyed. When interference is constructive, the intensity of the wave will increase. Interference can be either constructive or destructive. This shift will cause the wave to have interference with itself. The wave that passed through the slits was diffracted and will interfere with itself.ĭiffraction is caused by one wave of light being shifted by a diffracting object. Diffraction also occurs with as electrons.Ĭauses of diffraction A sketch of two-slit diffraction. Diffraction occurs with all waves, including sound waves, water waves, and electromagnetic waves such as light that the eye can see. ( October 2021)ĭiffraction pattern made by light passing through a single pinholeĭiffraction is a physics concept which occurs when waves bend around small obstacles, or spread out after they pass through small openings.
