What else can I help you with?
How long energy sun take to get to earth?
Energy, in the form of radiation, takes about 8 minutes to reach from the surface of Sun to the surface of Earth.
How does solar radiation reach the surface of the earth?
Solar radiation reaches the surface of the Earth through the process of electromagnetic radiation emitted by the Sun. This radiation travels through space and reaches Earth's atmosphere, where it penetrates and warms the surface of the planet. The atmosphere helps block harmful radiation while allowing sunlight to reach the surface.
How much of the Sun's radiation doesn't even reach Earth's surface?
Roughly 30% of the Sun's radiation is reflected back into space by the atmosphere, clouds, and surface of the Earth, before it reaches the planet's surface. This includes both direct reflection and scattering of solar radiation.
What kind of radiation passes through the atmosphere and reaches the earths surface?
Most of the visible light and some of the ultraviolet and infrared radiation from the sun pass through the atmosphere and reach the Earth's surface. Other forms of radiation, such as gamma rays and X-rays, are mostly absorbed by the atmosphere and do not reach the surface.
What penetrates the earth's atmosphere to reach the surface?
Electromagnetic radiation from the sun, most in the form of visible light.
How does the energy produced in the sun reach the surface?
Mainly by radiation - however, the radiation quickly gets absorbed by an atom, and re-emitted, so it takes quite a while to reach the surface. In the outer part of the Sun, the energy also gets transported through convection.
How does energy produced in the core of the sun reach the surface how long?
Mainly by radiation - however, the radiation quickly gets absorbed by an atom, and re-emitted, so it takes quite a while to reach the surface. In the outer part of the Sun, the energy also gets transported through convection.
What types of radiation can reach the surface of earth?
The types of radiation that can reach the surface of Earth include visible light, ultraviolet (UV) radiation, and some infrared radiation from the sun. Additionally, cosmic rays, which are high-energy particles from space, can also penetrate the Earth's atmosphere, although they are mostly absorbed. However, most harmful forms of radiation, such as gamma rays and X-rays, are absorbed by the atmosphere and do not reach the surface.
What is the shortest wavelenght radiation from the sun?
The shortest wavelength radiation from the sun is in the form of gamma rays, which have a very high frequency and energy. These rays are absorbed by the Earth's atmosphere and do not reach the surface.
What percent of the suns radiation is lost before reaching the earths surface?
Approximately 30% of the Sun's radiation is reflected back into space by clouds, atmospheric gases, and the Earth's surface. Additionally, about 20% is absorbed by the atmosphere, leaving around 50% of the Sun's radiation to reach the Earth's surface. This means that roughly 50% of the incoming solar radiation is lost before it reaches the ground.
Can you provide an example of how heat is transferred through radiation?
An example of heat transfer through radiation is when the sun's rays travel through space and reach the Earth, warming its surface.
The sun's radiation is most pronounced when it's strikes?
The sun's radiation is most pronounced when it strikes directly overhead, which occurs around solar noon. At this time, the sunlight passes through the least amount of atmosphere, allowing more radiation to reach the Earth's surface.
