According to this process, we conclude that some electrons were emitted by the zinc plate when exposed to ultraviolet light.
Electromagnetic theory of light :
The particles oscillate in perpendicular to the direction of travel of the wave motion.
Light is a electromagnetic wave that can be seen by the human eyes.
All electromagnetic waves can travel through a vacuum.
Hence, The electromagnetic theory of light.
