Your friend claims the light is a wave. What experimental evidence could you cite to demonstrate that light behaves like a particle?
The Nature of Light:
Whether light is a wave or a particle has been debated by scientists for several centuries. At the turn of the 19th century, certain assumptions about light led to the "ultraviolet catastrophe" -- a nonsensical prediction of classical physics that a blackbody would emit infinite ultraviolet energy for small wavelengths. The solution to this problem resulted from considering light as a series of packets called quanta. That is, light of a given frequency can not be infinitely divided, but has a fundamental discrete value that can not be subdivided further. In other words, light can behave as a particle.
