The order of the waves in the electromagnetic spectrum from lowest to highest frequency is:
radio waves     < 3 x 10^9 hz
microwaves           3 x 10^9 hz - 3 x 10^12 hz
infrared radiation   3 x 10^12 hz - 4.3 x 10^14 hz
visible light rays     4.3 x 10^14 hz - 7.5 x 10^14 hz
ultra violet radiation   7.5 x 10^14 hz - 3 x 10^17 hz
x-rays                       3 x 10^17 hz - 3 x 10^19 hz
gamma rays           > 3 x 10^19 hz
