Compared to radio waves, ultraviolet rays have the same speed
and much shorter wavelengths (much higher frequency).
When you get to the level of Physics where you start discussing
how light behaves like both waves and particles, then you'll learn that
the energy of each particle is proportional to its frequency, so a particle
of ultraviolet light carries more energy than a particle of radio does.
But you can make a beam of either one carry as much energy as
you want. For more energy, just use a stronger radio transmitter,
or a brighter ultraviolet light.
