Electromagnetic radiation consists of discrete packets of energy which are called as :
Answer: B
The discrete packets of energy are called photons.
Planck proposed that radiation is emitted in quanta, and Einstein's explanation of the photoelectric effect (1905) showed that light itself consists of particles of energy \(E = h\nu\), where h is Planck's constant and \(\nu\) the frequency. These quanta of electromagnetic radiation are photons; they have no rest mass and travel at the speed of light.
Quarks are the particles that make up protons and neutrons. Electrons are charged particles of matter, and positrons are their antiparticles. None of them is a packet of electromagnetic radiation.
