A ground station sends data using microwaves to a satellite above Earth’s atmosphere.
Why can the microwave signal from the ground station reach the satellite?
Microwaves pass through Earth’s atmosphere with little absorption.
Microwaves are absorbed by water in Earth’s atmosphere, which carries the signal.
Microwaves have the longest wavelength in the electromagnetic spectrum.
Microwaves travel faster through Earth’s atmosphere than other electromagnetic waves.
