What Is Wave Diffraction

diffraction, the spreading of waves around obstacles. … The phenomenon is the result of interference (i.e., when waves are superimposed, they may reinforce or cancel each other out) and is most pronounced when the wavelength of the radiation is comparable to the linear dimensions of the obstacle.

What causes diffraction of waves to increase?

Refraction is always accompanied by a wavelength and speed change. Diffraction is the bending of waves around obstacles and openings. The amount of diffraction increases with increasing wavelength.

What is an example of a diffraction wave?

The most common example of diffraction occurs with water waves which bend around a fixed object. Light bends similarly around the edge of an object. The animation shows wave fronts passing through two small openings. They visibly change direction, or diffract, as they pass through the opening.
