Correct Answer: B
Explanation:
Transverse waves are waves where the displacement of the particles in the medium is perpendicular to the direction the wave is travelling in. For example water waves.
Electromagnetic waves are oscillating electric and magnetic fields they include radio waves, microwaves, infra-red, visible light, ultra-violet, x-rays and gamma rays. Electromagnetic waves are transverse waves and they all travel at the speed of light (3 x 108 ms-1) in a vacuum.
Transverse waves can be polarized but longitudinal waves cannot. Un-polarized light is a mixture if waves in different planes. When this light is passed through a polaroid material only light waves in one plane are transmitted and the light is now polarized.
Refraction, interference, and diffraction are shown by both transverse and longitudinal wave, hence; cannot be used to differentiate the transverse and longitudinal wave.
