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.
That means that both the frequency and the wavelength of microwaves are also between those of infrared and radio waves.
False. For some bands of radio waves the atmosphere is transparent. Radio waves can penetrate to the ground. That's why we have radio telescopes on the Earth.
The frequency range that the radio waves can penetrate the human body is between 1Hz and 10 KHz. This frequency of the radio waves is however not dangerous.
I think the radio waves penetrate according to the barrier leakage or tunneling as explained by quantum mechanics.
Radio waves can penetrate interstellar gas and dust without being scattered or absorbed

the instrument used to gather radio waves is a special dish called a parabolic dish
Radio waves can penetrate materials such as walls, buildings, and certain types of soil more effectively than light waves. This is due to their longer wavelengths, which allow them to pass through obstacles that scatter or absorb visible light. For example, radio waves can travel through concrete and wood, while light waves are typically reflected or absorbed by these materials.
A special sort of ariel called a "radio telescope"
Yes, a radio telescope is an instrument specifically designed to detect and measure radio waves emitted by celestial objects in space. It is used to study and observe radio emissions from various astronomical sources, providing valuable information about the universe.
Yes.
Yes, radio waves can travel through plastic material. However, the ability of radio waves to penetrate through plastic may vary depending on the type of plastic and its thickness. Generally, thinner and more transparent plastics allow radio waves to pass through more easily.
