What electromagnetic waves are produced by stars and galaxies?
Stars and galaxies emit a broad range of electromagnetic waves including visible light, ultraviolet light, X-rays, and radio waves. The specific wavelengths and intensities of these emissions depend on the temperature, composition, and activity of the celestial object.
What kind of electromagnetic waves do the hottest stars give off?
The hottest stars primarily emit electromagnetic waves in the form of ultraviolet (UV) radiation. These stars, with surface temperatures exceeding 30,000 Kelvin, have significant energy output in the UV spectrum, which is much higher than that of cooler stars. Additionally, they also emit X-rays and visible light, but their peak radiation is typically in the ultraviolet range due to their high temperatures.
What kind of wave does the sun produce?
the sun produce ultraviolet rays which strike the earth surface.
Are rotating stars that emit directional beams of radio waves?
Yes, rotating stars can emit directional beams of radio waves. This phenomenon is known as pulsars, which are rapidly rotating neutron stars that emit beams of electromagnetic radiation, including radio waves, along their magnetic axes. The regular pulsing of these beams as they sweep across our line of sight gives the appearance of a pulsating or blinking star.
Are stars primary sources of light?
Yes, stars are primary sources of light. They produce light and heat through nuclear fusion in their cores, which results in the emission of energy in the form of light and other electromagnetic radiation.
When are no electromagnetic waves produce?
In a vacuum
Can rhythmic movement of air molecules produce electromagnetic waves?
No, the rhythmic movement of air molecules does not produce electromagnetic waves. Electromagnetic waves are generated by the oscillation of electric and magnetic fields and do not require a medium, such as air, to propagate.
What vibrated to produce electromagnetic waves?
An electric charge.
How are the distances to stars measured?
by the property of reflection or electromagnetic waves
Do stars have electromagnetic waves and how is it a known fact of this information?
Stars don't have electromagnetic waves. They absorb them and release them. It is not a known fact because electromagnetism is only a theory for now. However, light that reach us from stars are said to be EM waves because visible light is theorized to be in the EM spectrum.
Do electromagnetic waves need a medium?
No. We get electromagnetic waves from the sun. We can see stars and sun even though there is a virtual vacuum between us. Electromagnetic radiation or electromagnetic waves includes the radio and television signals that we can get from space satellites.Sound is not an electromagnetic wave, it needs a medium.
The energy produced by elctromagnetic waves?
Electromagnetic waves carry energy in the form of electromagnetic radiation. This energy can be transferred through space and can be converted into various forms, such as heat or electricity, when it interacts with matter. Examples of electromagnetic waves include light, radio waves, microwaves, and X-rays.
How do you produce electricity from electromagnetic waves?
Current flows through any conductor when electromagnetic waves fly past it. That's how a radio antenna works.
What radiation waves does an electric radio produce?
The radio receptor receives electromagnetic waves from a broadcast station.These waves are called radio waves. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.
Does the periodic acceleration of electrical charges produce electromagnetic waves?
Yes.
Can waves of the electromagnetic spectrum travel through a vacuum?
Yes, waves of the electromagnetic spectrum, including visible light and radio waves, can travel through a vacuum. This is because electromagnetic waves do not require a medium to propagate, unlike mechanical waves such as sound waves.
Which of the following produces electromanetic waves is it moving neuton?
No. Electromagnetic waves are produced by accelerating charges (NOT by moving charges, they have to accelerate); a neutron has no net electrical charge.
