Question

the phenomena which points towards corpuscular nature of electromagnetic wave is​

Answer 1

Explanation:

Each corpuscle always travels in straight line making definite angle with coordinate axis. This property of the propagation of corpuscles results the phenomenon of diffraction and interference.

Answer 2

Photoelectric effect points towards the corpuscular nature of the electromagnetic wave.

• Light has dual nature i.e. it shows both wave and particle nature.
• The particle/corpuscular nature indicates that light is made of small corpuscles that carry energy.
• Albert Einstien discovered that light behaves like a stream of energy-carrying packets called photons using the experiment of Max Planck called the photoelectric effect.
• When light with a suitable frequency is incident on metal, it ejects electrons from the atoms of the metal. This phenomenon of the ejection of electrons is called the photoelectric effect.
