what is diffraction? diffraction is the bending of a wave around objects or spreading after passing through a gap
_______ of light is the bending of light by means other than reflection or refraction? Diffraction
what happens to a wave when it is diffracted? the wave bends around obstacles causing it to spread out
what happens when a wave hits the boundary between two substances of an object face on? it continues on the same direction
when a wave goes through a wide slit it is ___________ it is unaffected
what is the interference pattern formed by diffracted light called? diffraction pattern
why does a single slit produce diffraction patterns? as light passes through the slit it diffracts at either edge of the slit, the waves interfere producing maxima and minima
when does Fresnel diffraction occur? It occurs in near field when the screen is held close to the aperture
when does Fraunhofer diffraction occur? It occurs in the far field or near the focal plane created by converging the light with a positive lens
What principle states that every point on a wave front acts like a point source of secondary wave lengths? Huygens principle
what is Huygens principle used to describe? It is used to describe the bending of light rays on interface between media with different refractive index and its propagation behind obstacles
what is a wavefront? a wave front is the line or curve of the crests and trough
