Diffraction

Shalini Jha asks:

“What is Diffraction?”

Answer:

Diffraction is the bending of a wave around obstacles in its path. The diffraction effects are prominent when the size of he obstacle is comparable to the wavelength of the wave.

Sound waves can bend around large obstacles as it has got a large wavelength. But light waves can bend only around tiny sharp obstacles as it has a short wavelength.

Question from Wave Optics

Rajat Asked:

What is the difference between interference and diffraction?

Ans:

Interference is caused by the superposition of wave fronts from two coherent sources; But diffraction is caused by the superposition of wavelets from a single wavefront when it confronts an obstacle or a slit.
