Unleash Your Understanding of Light Interference and Diffraction

Diffraction is the process by which a beam of light is spread out as it passes through an aperture or across the edge of an object.

The aperture (or hole or slit) has to be comparable to the wavelength of the wave.

An interference pattern is produced.

<p>An interference pattern for light is a region of light and dark areas created by the overlapping of multiple light waves.</p> Signup and view all the answers
