How does the energy of ultraviolet radiation compare to the energy of microwaves?
Ultraviolet radiation has less energy than microwaves, because ultraviolet radiation has a lower frequency.
Ultraviolet radiation has more energy than microwaves, because ultraviolet radiation has a higher frequency.
Microwaves have less energy than ultraviolet radiation, because microwaves have shorter wavelengths.
Microwaves have more energy than ultraviolet radiation, because microwaves have longer wavelengths.

as a longitudinal wave
as a surface wave
as a transverse wave
as an electromagnetic wave
