How much time does it take for sunlight to reach the Earth?
Infrared light from the Sun provides about 50 percent of the solar energy that reaches Earth in the form of heat. Without it, our planet would be a much colder place. The rest of the heat energy comes from light in the visible spectrum range that, after it is absorbed, radiates back into the atmosphere in the form of heat.
Photons in the Radiative Zone
At that point the convection currents take over and carry the sun''s energy to the photosphere on seething rivers of hot gases. Although it may have taken the photons a million years to reach the convection zone, the energy they deliver rises through the entire convention zone in about three months. All the energy emitted at the surface of the ...
