What else can I help you with?
What was invented in 1932?
radio waves
Do radio waves need medium to travel?
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.
Which EM waves can carry television signals?
Radio waves. Low frequency.
How a triode works as basic amplifier?
A triode works as a basic amplifier by the use of radio waves. The radio waves produce a heat that is amplified.
On the electromagnetic spectrum microwaves are located between infrared waves and radio waves. Which is true for microwaves?
That means that both the frequency and the wavelength of microwaves are also between those of infrared and radio waves.
Neither X rays nor radio waves can penetrate the earth's atmosphere?
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.
What is the frequency range of radio waves that can penetrate human body?
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.
What is the penetration of radio waves?
I think the radio waves penetrate according to the barrier leakage or tunneling as explained by quantum mechanics.
What characteristic of radio waves makes them useful for determining the shape of the galaxies?
Radio waves can penetrate interstellar gas and dust without being scattered or absorbed
What characteristic of radio waves makes them useful for determining the shape of a galaxy?
Radio waves can penetrate interstellar gas and dust without being scattered or absorbed
What characteristics of radio waves makes them useful for determining the shape of a galaxy?
Radio waves can penetrate interstellar gas and dust without being scattered or absorbed
What instrument used to gather information by bouncing radio waves off their surface?
the instrument used to gather radio waves is a special dish called a parabolic dish
What kind of material can radio waves penetrate that light waves cannot?
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.
What instrument collects radio waves from space?
A special sort of ariel called a "radio telescope"
Is the radio telescope an instrument which measures radiation?
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.
Can radio waves travel through plastic?
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.
How are radio-telescopes reveal that space is full?
Radio telescopes reveal that space is full by detecting radio waves emitted by various cosmic phenomena, such as pulsars, quasars, and interstellar gas clouds. These observations allow astronomers to map the distribution of matter in the universe, including dark matter and cosmic structures. Additionally, radio waves can penetrate dust and gas that obscure other wavelengths, providing a clearer view of the universe's contents. This extensive data collection confirms that space is not empty but filled with diverse and complex structures.
