Question

Is light a particle?

Answer 1

Light

1. Light has the properties of both a particle and a wave.
2. The nature of light is twofold:
3. It can act like a particle (photons) at times, which is why light travels in a straight line.
4. Light can behave like a wave at times, which explains how light bends around an object.

Light as a Wave

1. An electromagnetic wave is how light is described.
2. Electromagnetic waves are waves that are formed when an electric field and a magnetic field vibrate together.
3. Electromagnetic waves, unlike many other waves, do not require a medium to move.

Light as Particles

1. The particle nature of light is supported by the photoelectric effect of light.
2. Light, according to Einstein, is made up of photons.
3. He claimed that photons contain energy equal to "Planck's constant" multiplied by the frequency of oscillation.

Hence, light can be considered a particle.
