JEE Main 2002 Physics question

Electromagnetic waves are transverse in nature is evident by

(1)polarizationCorrect
(2)interference
(3)reflection
(4)diffraction

Answer: (1)

Solution

Polarization (restricting vibrations to one plane) is possible only for transverse waves; longitudinal waves cannot be polarized. Hence polarization proves that EM waves are
