_are particles of light.
a. Proton
b. Electrons
c. Photons
d. Neutrons
Answer C
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. The energy of a photon
depends on its wavelength: longer wavelength photons have less energy and shorter wavelength
photons have more.
