the lonosphere
The upper layer of the atmosphere is the layer of atmosphere that has proven very useful to people because it reflects radio waves. Radio waves are a type of electromagnetic radiation.
UV rays are not reflected, but absorbed. They are absorbed by ozone in the stratosphere. This is what causes the stratosphere to warm with altitude.
eeee
radio waves
The mesosphere is where meteorites burn up. Most people call them shooting stars.
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.
Radio waves. Low frequency.
A triode works as a basic amplifier by the use of radio waves. The radio waves produce a heat that is amplified.
Lonosphere
Ionosphere
the ionosphere.
the lonosphere
The ozone layer contains electrical charged particles that reflects radio waves
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.
Exosphere (Thermosphere).
Ionosphere
The ozone layer contains electrical charged particles that reflects radio waves
The troposphere... It acts like a gigantic mirror - reflecting radio waves back to Earth.
The ionosphere - specifically the e-layer
