A) interference of light
B) diffraction
C) radiation spectrum of a black body
D) polarization
Correct Answer: D
Solution :
Polarisation is the property of electromagnetic waves, such as light, that describes the direction of their transverse eletric field. More generally, the polarisation of transverse wave describes the direction of oscillation in the plane perpendicular to the direction of travel. Longitudinal waves such as sound waves do not exhibit polarization, because for these waves the direction of oscillation is along the direction of travel.
