Properties of Light

Postby Anthony_Imperial_1G » Sun Oct 09, 2016 12:00 am

Hey everyone. I just wanted some people to clarify if light had properties relating to waves. In the video module about the photoelectric effect, Prof. Lavelle said that light did not increase in energy whenever the frequency increased, therefore saying that light does not have wave properties. But in a recent lecture, he then said that light DOES have wave properties. Does light have properties of waves in ever scenario except in the photoelectric effect?

Many of light's behaviours can be explained by the wave model (such as diffraction with the diffraction patterns), but it is the photoelectric effect in which we can only explain light's behaviour with the particle model (photons). I'm not sure if it would be exactly correct to think of it as light having wave-like properties in every other situation except in the photoelectric effect, as reflection and refraction can be explained with the particle model as well. But in general, light demonstrates wave-like properties most of the time, except for in the photoelectric effect.
