DIFFRACTION

DIFFRACTION

1. It is a phenomenon characteristic of waves that consists of the apparent curved dispersion of waves when they encounter an obstacle

2. another definition

   • any bending of light by means other than reflection and refraction

3. example

   • when you touch your finger to the surface of still water,circular ripples are produced
     • another example
       • when you touch the surface with a straightedge, such as a horizontally held meter stick, you produce a series of a plane waves by successively dipping a meter stick into the surface of the water

4. Diffraction occurs in all types of waves

   • Desde ondas sonoras, ondas en la superficie de un fluido o ondas electromagnéticas
     • ex
       • The sound waves When the wave hits an opening or an obstacle that prevents its propagation, all the points of its plane become secondary sources of waves emitting new waves called diffracted waves.
