Concept // Wave-like Behavior

Aside from diffraction, what is another evidence that shows that electromagnetic radiation behaves like waves?

I believe the way light reflects, refracts, diffracts, and interferes all point to its wave-like characteristics.

So, since the emission of electrons is not dependent on the level of intensity that the light is, will changing the wavelength effect its emission?

I'm assuming the its refers to electrons. With that assumption, the changing of the wavelength will effect the emission of the electron. For the electron to be emitted the wavelength has to be lower than the cutoff wavelength for the particular metal. As long as the changed wavelength is lower than the threshold wavelength, and the required energy is present, then the emission of the electron shouldn't be effected.

Re: Concept // Wave-like Behavior

I'm pretty sure that if you change the wavelength, you do affect the ejected electron. As the wavelength shortens, you end up with a higher energy from the photon, which in turn transfers a larger kinetic energy to the ejected electron. The number of electrons set off by one photon is always one though; therefore, higher energy photons will only cause the electrons ejected at a higher kinetic energy, but only one electron will be ejected by one photon.
