The sun emits EM radiation by the process of nuclear fusion. The gamma rays that are produced in the core are scattered and absorbed in the sun by the plasma. The gain in KE of some of the particals that undergo nuclear fusion also helps to heat up the sun.
Does the sun give out electromagnetic waves?
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
What electromagnetic waves make up sunlight?
Though the sun emits all of the different kinds of electromagnetic radiation, 99% of its rays are in the form of visible light, ultraviolet rays, and infrared rays (also known as heat).
How does energy from the sun enter the atmosphere?
Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. Most of the energy that passes through the upper atmosphere and reaches Earth’s surface is in two forms, visible and infrared light. … This transfer of energy can take place by three processes: radiation, conduction, and convection.
How does the sun produce visible light?
Visible light, for example, comes from the photosphere (or surface) whereas most infrared light comes from the lower chromosphere just above. Much of the high-energy UV and X-ray photons come from the Sun’s outer atmosphere (called the corona).
How does the sun produce light?
The Sun produces light by a nuclear reaction called fusion. As atoms of hydrogen combine to form helium, they produce vast amounts of heat and light. Sunlight appears white, but it contains a mixture of all the colours of the rainbow: red, orange, yellow, green, blue, indigo, and violet.
What happens to the light coming from the sun?
In the case of the sun, what happens is that all the newly formed light from the core hits the inner layer of the radiation zone and is absorbed. This zone is opaque to light, so it’s constantly being absorbed and then spat back out by the atoms in the radiation zone.
Which of the following absorb the energy from the sun?
About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system.
What type of electromagnetic energy does the sun emit most intensely?
The electromagnetic waves emitted by the sun are of a broad spectrum ranging from X-rays with a wavelength of 2 nanometers to radio waves with a wavelength of 10 meters. The most intense of these to reach the earth’s surface is visible light, with a wavelength around 500 nanometers.
