Question 3

A satellite communicates with a ground receiver station on Earth using high-frequency microwaves.

Read these statements about the interaction of the microwaves with different media:

  1. When the microwaves pass through a wet storm cloud, water droplets _________ the signal by absorbing and scattering some of the wave's energy.

  2. If the microwaves encounter a large, flat metallic structure, they are _________ by the conducting surface, which behaves like a mirror at these wavelengths.
