Light and water waves are transverse waves. A wave in which the vibration of particles in the medium which is perpendicular to the direction of the propagation of waves. Light waves : vibration of electrons in an atom. Water waves : Vibration on a still water surface. Sound waves are longitudinal waves are slower than light waves, and do not travel through a vacuum. This is why you see a lightning before you hear it. Electromagnetic waves : -Oscillation between the electric field and the magnetic field. -A type of transverse waves -Do not require a medium, able to travel in vacuum. -In vacuum, they travel at the speed of light (c =3x10^8 ms/1) -The energy is transferred by the waves -Includes : radio wave, microwave, infrared, visible light, ultraviolet, x-rays, gamma rays.
