Question

why does we said that electromagnetic radiation have dual behavior? ​

Answer 1

Answer:

These packets of energy can be treated as particles. On the other hand, radiations exhibit a phenomenon of interference and diffraction which indicated that they possess wave nature. So it may be concluded that electromagnetic radiations possess dual nature.

Answer 2

Answer:

Scientists have observed that electromagnetic radiation has a dual "personality." Besides acting like waves, it acts like a stream of particles (called "photons") that have no mass. The photons with the highest energy correspond to the shortest wavelengths.

These packets of energy can be treated as particles. On the other hand, radiations exhibit a phenomenon of interference and diffraction which indicated that they possess wave nature. So it may be concluded that electromagnetic radiations possess dual nature.
