It's this magical place called a "university"

I'm extremely confused about light. It's a transverse wave, right? so therefore it must be going through a medium, if so which medium does it travel through (as it travels through vacuums). However I got more confused when reading about photoelectric emission, because the way it was explained in the textbook was individual photons of certain frequencies which carried enough energy to move electrons. If this is the case, then i assume that photons are the waves themselves, as that's the only way an individual thing having a "frequency" makes sense to me. But if this is the case, does it mean that some photons are larger than others due to differences in wavelengths? Pls help me understand this
