What is true about the stratosphere's effect on radio waves?

The stratosphere has little effect on radio waves primarily due to its composition and density. Unlike the ionosphere, which is located higher in the atmosphere and can reflect certain frequencies of radio waves, the stratosphere remains relatively stable and does not have ionization, meaning it doesn’t significantly enhance or disrupt radio communications.

The stratosphere is primarily composed of ozone and is less dense compared to lower atmospheric layers. This results in a condition where most radio waves can pass through with minimal scattering or absorption. The impact of the stratosphere is negligible in terms of changing the properties of radio waves because the frequencies used for most communication are not significantly affected by the atmospheric conditions found in this layer.

In contrast, other atmospheric layers or conditions might actively absorb, reflect, or disrupt radio wave propagation. Understanding the characteristics of different atmospheric layers is essential for effective communication and radio wave transmission.
