Question

How does the ionosphere help radio transmission?

Answer 1

Step-by-step explanation:

ionosphere can reflect radio waves directed into the sky back toward the Earth

Answer 2

Due to the ability of ionized atmospheric gases to refract high frequency (HF, or shortwave) radio waves, the ionosphere can reflect radio waves directed into the sky back toward the Earth. Radio waves directed at an angle into the sky can return to Earth beyond the horizon.
