Question

which of the choices arranges the components of the electromagnetic spectrum in order of increasing energy?
infrared, visible, ultraviolet, microwaves, x-rays
x-rays, microwaves, visible, infrared, ultraviolet
visible, ultraviolet, infrared, microwaves, x-rays
microwaves, infrared, visible, ultraviolet, x-rays

Explanation:

Electromagnetic energy increases with frequency (and decreases with wavelength). From lowest to highest energy, the order is microwaves < infrared < visible light < ultraviolet < x-rays, as microwaves have the longest wavelength/lowest frequency, and x-rays have the shortest wavelength/highest frequency among these options.

Answer:

microwaves, infrared, visible, ultraviolet, x-rays
