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

Both light and wave.

Explanation:

Experimental evidence shows that light can act as both a wave and a particle. Experiments such as Young's double-slit interference and the Michelson interferometer show that light acts as a wave. Experiments which use Einstein's photoelectric effect show that light can behave like a particle (called a photon)with discrete energy values. You can easily find other examples and more information on these topics with a little research.
