A) origin of spectra
B) refraction
C) reflection
D) diffraction
Correct Answer: A
Solution :
Huygens-Fresnel principle is a method of analysis applied to the problems of wave propagation. It recognizes that each point of an advancing wave front is in fact the centre of fresh disturbance and the source of a new train of waves. It is successful in explaining the phenomenon of reflection, refraction and diffraction but not the origin of spectra.
