Meaning and Definition
A radio wave that travels upwards, is reflected or refracted by the ionosphere, and returns to Earth, enabling long-distance communication.
In technical contexts, a method of radio propagation used for transmitting signals over long distances by utilizing layers of the Earth's atmosphere. In a broader metaphorical sense, it can refer to any communication signal that travels through or is reflected from the sky.

FAQ
Frequently Asked Questions
It is standardly written as two separate words: 'sky wave'.
No, a sky wave is a method of radio signal propagation, not a sound. The signal carried by the sky wave can be converted into sound by a radio receiver.
The main opposite in radio propagation is a 'ground wave', which travels along the Earth's surface.
Yes, while satellite and cable are dominant for many uses, sky wave (HF) propagation remains crucial for long-distance aviation/marine communication, international broadcasting, and amateur radio.
A radio wave that travels upwards, is reflected or refracted by the ionosphere, and returns to Earth, enabling long-distance communication.
Sky wave is usually technical in register.
Sky wave: in British English it is pronounced /ˈskaɪ ˌweɪv/, and in American English it is pronounced /ˈskaɪ ˌweɪv/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of the SKY as a giant mirror for radio WAVEs, bouncing signals from one side of the Earth to the other.
Conceptual Metaphor
COMMUNICATION IS A JOURNEY (the signal travels up to the sky and back down). THE IONOSPHERE IS A MIRROR/REFLECTOR.
