Light is an electromagnetic wave emitted by hot objects like lasers, bulbs, and the sun. Light is a type of kinetic energy that allows us to see or make objects visible with our eyes. The human eye can see light energy, which is a type of electromagnetic radiation. Photons are tiny energy packets that makeup light. The heat creates an electric current, which results in an increase in energy. The energy is released in the form of a photon, and as the substance heats up, more photons are emitted.
What is wave-particle duality?
Where h is the Planck constant
for a particle of momentum mv, the wavelength is given by λ=h/mv
Process that proves the wave nature of light
Few processes that prove the wave nature of light are listed below.
- Photoelectric effect
- Emission by atoms
