DIFFRACCION

DIFFRACCION

1. The process by which a beam of light or other system of waves is spread out as a result pf passing through a narrow aperture or across an edge,typically accompanied by interference between the wave forms produced.

2. Refers to various phenomena that occur when a wave encounters an obstacle a slit.is defined as the bending of light around the corners of an obstacle por aperture into the region geometrical shadow o the obstacle.in classical physics,the diffraction phenomenon is described as the inference of waves according to the huy gens fresnel principle.

3. diffraction occurs with all waves,including sound waves,water waves,and electromagnetic waves such as visible light,x-RYS and radio waves.

4. is a change in the direction of sound wave or a light wave caused by the presence of an obstacle in its path.

5. a deviation in the direction of wave at the edge of an obstacle in its path. any phenomenon caused by diffraction and interferencee of light, such as the formation of light and dark fringes by the passage of light thorough a small aperture.deflection of sound waves caused ny an obstacle or by nonhomogeneity of a medium

6. FOR EXAMPLE:The effects of diffraction are often sen in every life.the most striking examples of diffraction are those that involve lightfoot example,the closely spaced tracks on a CD or DVD acts a diffraction grating to form the familiar rainbow latterns sen when looking at a disc.
