A wave passes through an opening in a barrier.

The amount of diffraction experienced by the

wave depends on the size of the opening and the

wave's

(1) amplitude (3) velocity

(2) wavelength (4) phase

(2) wavelength. Diffraction is the slight bending of waves as it passes through apertures or around the edges of objects. The amount of bending depends on the relative size of the wavelength of light to the size of the opening in the barrier.
