radio waves
Radio waves. Low frequency.
light waves do not need a medium. Electromagnetic Waves (EM) do not need a medium. For example visible light, radio waves, microwaves, UV light and x-rays do not. These travel @ 300 million meters/sec in a vacuum.
A triode works as a basic amplifier by the use of radio waves. The radio waves produce a heat that is amplified.
The mesosphere is where meteorites burn up. Most people call them shooting stars.
The ionosphere is the layer of the atmosphere that reflects radio waves. This layer is able to reflect specific frequencies of radio waves back to Earth, allowing for long-distance communication using radio signals.

Ionosphere
the lonosphere
The ozone layer contains electrical charged particles that reflects radio waves
The ionosphere layer of the atmosphere is where reflection of waves for worldwide radio communications takes place. This layer is able to reflect radio waves back to Earth, allowing for long distance communication via the ionosphere's ionized particles.
It's not radio active waves; it's just radio waves. It's called the Ionosphere and depending on what layer of the Ionosphere it changes how far you can talk
The "F" layer is high altitude region of ionized atoms that reflects radio waves.

The troposphere... It acts like a gigantic mirror - reflecting radio waves back to Earth.
The ionosphere - specifically the e-layer
