LIGHT IS TRANSVERSE

In transverse wave,the particles vibrate perpendicular to the direction of wave propagation.

“light is a transverse wave.”
but light can be propagated without a medium , that is particles.
so, how can light be called as a transverse wave?

Answer:

Light is an electromagnetic wave which requires no medium for the propagation. In electromagnetic waves including light, electric and magnetic fields vary with time in mutually perpendicular directions and also perpendicular to the direction of propagation.

Transverse nature of light

Mallika Somnath asks:

it is said that in tranverse waves the particles move perpendicular to the direction of motion of wave.
it is also said that light is a transverse wave.
but how can the particles in light move at all, as light doesn’t require a medium to travel?

Answer:

Light is an electromagnetic wave, energy propagated as a combination of electric and magnetic fields varying with time in mutually perpendicular directions, also perpendicular to the direction of propagation. This makes light a transverse wave.
