Question - Which atmospheric layer contains Ions and helps in wireless communication?

Which atmospheric layer contains Ions and helps in wireless communication?

a) Mesosphere

b) Thermosphere

c) Troposphere

d) Stratosphere

Answer: b) Thermosphere

The thermosphere is located between about 80 and 400 kilometers above the mesopause. It contains electrically charged particles known as ions; therefore, it is also called the ionosphere. Radio waves transmitted from Earth are reflected back to the planet by this layer. Because it contains ions, the thermosphere plays a crucial role in wireless communication.
