All electromagnetic waves, including light, are transverse waves because they vibrates energy in a direction perpendicular to the direction in which the wave is travelling. However, light is an exception as it is not only a transverse wave, it is an electromagnetic wave, which can travel through any medium.
What type of wave is a light wave?
Electromagnetic waves are made of oscillating magnetic and electric fields and, like all waves, they carry energy. There are many types of electromagnetic waves. From lowest energy to highest energy (red to blue) there are radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays.
