\nLight waves are electromagnetic waves, which means they are fluctuations of electric and magnetic fields. Electromagnetic waves, including light, are characterized by their transverse nature, where the oscillations of the fields are perpendicular to the direction of wave propagation.
\n<\/section>\n
\nTransverse waves have oscillations perpendicular to the direction of energy transfer (propagation).
\nLongitudinal waves have oscillations parallel to the direction of energy transfer (propagation), like sound waves in air.
\nLight is non-mechanical; it does not require a medium to travel.
\n<\/section>\n
\nThe electromagnetic spectrum includes various types of waves like radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays, all of which are transverse electromagnetic waves.
