Diffraction is the name given to the:
Correct answer: B. Bending of waves round an obstacle
- A. Addition of two coherent waves to produce a stationary wave pattern.
- B. Bending of waves round an obstacle
- C. Change of direction when waves cross the boundary between one medium and another.
- D. Splitting of white light into colours.
Explanation
Diffraction is the spreading of waves around obstacles.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
