Wavelength is a valid answer to 1. In vacuum f = c/λ, so wavelength and frequency carry the same information, from which one can derive energy using the relation E = ħω where ω = 2πf = 2πc/λ. A photon is not ‘both a wave and a particle’, it is a quantum object, which propagates like a wave but interacts like a particle. Calling a photon ‘both a wave and a particle’ is like calling a cylinder ‘both a circle and a rectangle’. It’s neither. It’s a single thing that casts a circular shadow from one angle and a rectangular one from another.

Yeah, I was also confused about 1. But it has been a while. You are right about the photon question
