Properties of Light (Particle and Wave)

Although we say that light is a wave and it displays wave characteristics, it does display particle
nature as well. We call the light that displays particle nature as photon and it is not considered a
wave. Therefore, light is seen as having dual nature. As a wave, light has wavelength and
frequency and it interferes with each other. As a particle, which is called a photon, it has
momentum and it can push electrons off a surface of metal when light is shone on it. As a
particle light has speed, which is same as c, and it can give off its momentum. However, a
photon does not have mass.
