The layer of the atmosphere which efficiently reflects high frequency waves particularly at night is
Show Hint
The ionosphere, which is part of the Thermosphere, is responsible for reflecting radio waves for long-distance communication (skywave propagation). At night, the lower absorbing layers of the ionosphere weaken, allowing HF waves to reach the higher F layer, which reflects them back to Earth efficiently.
