Diffraction is the spreading of light that takes place when it pass through a thin slit or small hole or passes by an obstacle
Answer:
Diffraction is the spreading of any kind of wave that take place upon passage of that wave by an obstacle or through a thin slit or small hole. Light is a type of wave so the statement is true.

Light is quantized. Photons are light quanta. It has zero REST mass. Therefore, it always travels at maximum speed permitted by relativity.
As a longitudinal wave moves through a medium, the particles of the medium: a) vibrate in a path parallel to the path of the wave b) vibrate in a path perpendicular to the p
Difference among sound and light waves: (i) For propagation of sound rays material phase is required but no material medium is needed for light waves. (ii)Sound rays are long
