The sun emits electromagnetic energy pretty much across the electromagnetic spectrum. Pick a low radio frequency and the sun emits electromagnetic energy in that band. The sun emits all kinds of electromagnetic (EM) energy. From the higher frequencies (higher energies and shorter wavelengths) down, out star emits gamma rays, X-rays, ultraviolet (UV) rays, visible light, infrared (IR) rays, microwaves, high frequency radio frequency (RF) waves and all the rest. Radiation from the sun interferes with AM radio in the 520 - 1700 kHz band, and even lower frequency electromagnetic energy like the very low frequency (VLF) bands used in . We can "see" or "hear" the electromagnetic noise of the sun just about anywhere we care to look or listen (depending on which word you prefer) with optical or radio telescopes, or even a longwave radio reciever.
What else can I help you with?
What is it called when earth blocks the sun's rays from reaching it?
It is called an eclipse when Earth blocks the sun's rays from reaching it.
How does the length of day effect the amount of energy reaching the Earth?
The earth's prbit around the sun is not circular, it is an ellipse. the earth is further from the sun at the ends of the ellipse than when it is in the middle. The length of day is a local effect, based on the angling of the earth's axis towards the sun. When the days are longest in the northern hemisphere they are shortest in the southern hemisphere, and vice versa. These days occur when the earth is at its orbit's greatest distance from the sun. When the days are closest to being as long as the nights, the earth is at its orbit's shortest distance from the sun. When the earth is nearest the sun it receives a greater amount of energy than when it is further away.
Which inner planet takes the longest to orbit the sun?
Mars takes the longest of the inner planets.
How does the sun get its color?
The sun appears yellow because its light is composed of a range of colors, with shorter wavelengths like blue and violet scattered by the Earth's atmosphere. This scattering causes the longer wavelengths, such as yellow and red, to dominate and give the sun its overall yellow color when seen from Earth.
Which planet takes the longest time in going round the sun once?
Neptune takes the longest to revolve around the sun.
What is an eclispe?
When the moon blocks the Sun's light from reaching Earth, and also when our planet Earth blocks the Sun's light from reaching the moon.
What is it called when earth blocks the sun's rays from reaching it?
It is called an eclipse when Earth blocks the sun's rays from reaching it.
Which type of radiation from the sun is the longest wavelength?
Radio waves are at the long wavelength end of the sun's emissions.
Where is the sun during the longest shadow?
The sun is low on the horizon, such as during sunrise or sunset, when shadows are at their longest. This creates the elongated shadows as the light has to travel through more of the Earth's atmosphere before reaching the objects casting the shadows.
Which is the longest distance from sun to earth?
Aphelion
Can humans see all the wavelengths or light that arrive on earth from the sun?
no

When the earth is nearest the sun it receives a greater amount of energy than when it is further away.
When the moon is between the earth in the sun?
When the moon is directly between the earth and the sun, it's a solar eclipse, because the moon blocks the light from the sun from reaching the earth.
What are the longest and shortest distances from the earth to the sun?
The longest distance from Earth to the Sun is about 94.5 million miles (152 million kilometers) in July when Earth is farthest from the Sun (aphelion). The shortest distance is about 91.5 million miles (147 million kilometers) in January when Earth is closest to the Sun (perihelion).
Is it true that During a lunar eclipse Earth's shadow blocks light from reaching the sun?
No. Earth's shadow blocks sunlight reaching the Moon.
What causes the difference between the sun and earth's radiation wavelengths?
Unlike Earth and other solid objects, the entire Sun doesn't rotate at the same rate of gas and plasma, different parts of the Sun spin at different rates.
Why do the earth receive a distribution of wavelengths instead of just one?
The Sun light is not monochromatic.
