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?
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.
