How are radio waves affected in the atmosphere?
Radio waves can be affected in the atmosphere by factors such as absorption, reflection, refraction, and scattering. Absorption occurs when radio waves are absorbed by molecules in the atmosphere, which can weaken the signal. Reflection can cause radio waves to bounce off the different layers of the atmosphere, affecting their path. Refraction can change the direction of radio waves as they pass through different layers of the atmosphere, leading to signal distortion. Scattering can cause radio waves to be dispersed in different directions, reducing the signal strength.
