Hi,
Shortwave, Mediumwave and Longwave are consumer terms referring to the wavelength. Amateurs refer to wavelengths in specific lengths, such as a wavelength of 40 metres.
There is no direct connection between wavelength and modulation.
Sideband is not a form of frequency modulation. For Foundation, you can assume FM, AM and SSB (single sideband) as separate modulation types.
