Question

What is quantum nature of electromagnetic radiation?

Answer 1

Answer:

Photoelectric effect shows the quantum nature of electromagnetic radiation. This effect was discovered by Hertz in 1887. When light of appropriate frequency is incident on metallic surface,electrons are liberated from that surface.The observation is known as photoelectric effect.

Explanation:

• What is a quantum of electromagnetic radiation?

A quantum of electromagnetic energy is called a photon. Visible light and other forms of electromagnetic radiation may be thought of as a stream of photons, with photon energy directly proportional to frequency. ... Electromagnetic radiation of different frequencies interacts with matter differently.

• What is quantum nature of radiation?
• Although classical physics had explained most of its behavior as a result of its wave nature, Planck and Einstein showed that electromagnetic (EM) radiation behaves as if its energy is carried at the nanoscale in small bundles, or quanta (plural of quantum), of energy with particle-like characteristics.
