Q. Which subatomic particles is the lightest Why?
Electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton.

Q. What is lightest sub atomic particle of the atom?
Electrons – The lightest subatomic particle is the electron at 9.11×1031 kg. It is almost massless in comparison to protons and neutrons and behaves like both a wave and a particle. The electron is one of the lightest subatomic particles and one of the key components of atoms, along with neutrons and protons.
Q. Can a photon have zero energy?
The speed of a photon does not affect its energy. It has zero mass, therefore zero kinetic energy. The energy it has is due to its frequency (color), and nothing else. (However, it does have momentum!)
Q. Is light a particle or a wave?
Light Is Also a Particle! Einstein believed light is a particle (photon) and the flow of photons is a wave. The main point of Einstein’s light quantum theory is that light’s energy is related to its oscillation frequency.
Q. Who gave wave nature of light?
However, it was a British erudite and physician called Thomas Young who convincingly demonstrated the wave nature of light –contrary to the ideas of Newton who believed light was composed of a stream of particles– through the double-slit experiment, known today as Young’s light-interference experiment.
Q. Why does light behave like a particle?
Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. They also found that increasing the intensity of light increased the number of electrons ejected, but not their speed. …
Q. Why does light exist?
Looking deeper into the mathematics, we find that their existence explains how charged objects feel a force from the field: they emit and absorb photons. So, one answer to the question “why do we have light?” is simply that photons must exist to preserve local gauge symmetry.
