Light is indeed an electromagnetic wave. It is a form of electromagnetic radiation that can be perceived by the human eye. Electromagnetic waves consist of oscillating electric and magnetic fields that propagate through space.
Light is classified as a transverse wave. In a transverse wave, the oscillations of the electric and magnetic fields occur perpendicular to the direction of propagation. This means that as light travels, the electric and magnetic fields vibrate in directions that are perpendicular to the direction in which the light is moving.
Transverse waves are different from longitudinal waves, where the oscillations occur parallel to the direction of propagation. In the case of light, it exhibits a transverse nature, and this property is what allows for many of the phenomena associated with light, such as interference, diffraction, and polarization.
