Which of the following phenomena establishes the transverse nature of light waves?

• This is a process by which unpolarised light is transformed into polarized light.
• Polarisation tells about the wave nature of light, as the light wave is polarised in a particular plane.
• The longitudinal waves cannot be polarised.
• Polarization does not work on the longitudinal wave.
• Only transverse waves can be polarized.
• By the phenomenon of polarization, electromagnetic waves show transverse nature.

Additional Information

Diffraction:

• It refers to various phenomena that occur when a wave encounters an obstacle or a slit.
• It is defined as the bending of waves around the corners of an obstacle or through an aperture into the region of the geometrical shadow of the obstacle/aperture.
• Example: The rainbow pattern found on a CD.

1) The wave which is generated due to vibration between electric field and magnetic field and it does not need any medium to travel is called an electromagnetic wave. It can travel through a vacuum.

2) Light is a form of energy which is an example of electromagnetic waves.

3) Electromagnetic waves are transverse in nature because they propagate by varying their electric and magnetic fields so that both the fields propagate perpendicular to each other.

Compton effect is defined as the effect that is observed when x-rays or gamma rays are scattered on a material with an increase in wavelength.

1) Arthur Compton studied this effect in the year 1922.

2) During the study, Compton found that wavelength is not dependent on the intensity of incident radiation.

3) It is dependent on the angle of scattering and on the wavelength of the incident beam.
