Microwaves is a form of electromagnetic waves like light.
Answer: Option A
Step-by-step explanation:
Electromagnetic spectrum constitutes a broad classification of waves of different wavelength starting from radio waves to gamma rays. Microwaves are in the order of Giga hertz (i.e) 10^9 where it finds major applications like antennas used in the television, frequency of FM radio channels, cellular phones, e.t.c.
Their wavelength ranges from 1 meter to one millimeter. The sun is also capable of emitting microwaves where most of them are observed by the earth's atmosphere.
