Is light a wave or a particle? Support your answer by citing specific experimental evidence.

Answer #1

Light acts both as a wave and as a particle. In some situations it behaves like a wave and in other it behaves like a particle.

Evidence of Wave like behaviour of Light

Light reflects,refracts and diffracts in the same way as any wave would. Light undergoes interference as a wave as demonstrated by the Youngs Double Slit experiment. Light also exhibits Doppler effect as a wave.

Evidence of Particle like behaviour of Light

Light is made up of collection of photons( light particles ). Light as a particle is demonstrated by Photoelectric Effect in which when light is shined on a metal it ejects electrons.

Just as light waves have particle behavior, a moving particle has a wave nature. The faster the particle is moving, the higher its kinetic energy and the shorter its wavelength. The wavelength, λ, of a particle of mass m, and moving at velocity v, is given by the de Broglie relation λ=hmv where h=6.626×10−34 J⋅s is Planck's constant. This formula applies to all objects, regardless of size, but the de Broglie wavelength of macro objects is miniscule compared to their...

Describe the experimental evidence and reasoning that led 19th century physicists to conclude that light has wavelike properties. In doing this, you should discuss at least one semal experiment, and explain what was known about the properties of light before the experiment, what key piece of evidence from this experiment changed physicists' understanding of light , and describe the new understanding of the physical nature of light that developed as result of this experiment.
