Which consequence results when a radio wave encounters significant ionospheric density gradients?

💡 Explanation

Radio waves experience Faraday rotation because the differing phase velocities in ionospheric layers results in polarization shifts due to birefringent effect. Therefore polarization shifts are detected rather than altered noise because signal strength is impacted as layers vary.
