Is microwave a type of light?

Microwave is a color of light, too low-energy for you to see, lower-energy even than infrared, but higher-energy than radio. Microwave ovens produce large amounts of this light. Because of the size of the light waves (micrometers, hence the term microwave), they are capable of spinning water molecules as they go past.
