Question

what type of wave are light waves? longitudinal transverse

Explanation:

Light waves are electromagnetic waves. Electromagnetic waves are transverse waves. In transverse waves, the particles of the medium vibrate perpendicular to the direction of wave propagation. Light does not require a medium to travel and its electric and magnetic fields oscillate perpendicular to the direction of its propagation. Longitudinal waves have particle vibration parallel to wave direction (e.g., sound in air), which is not the case for light.

Answer:

transverse
