How does the photons of the sun get to Earth?

You probably know that photons are created by fusion reactions inside the Sun’s core. They start off as gamma radiation and then are emitted and absorbed countless times in the Sun’s radiative zone, wandering around inside the massive star before they finally reach the surface.

Where do most of the photons that reach the Earth come from?

The vast majority of light that makes it to Earth’s surface comes from the nearby star, which spits out 1,368 watts of power to every square meter of Earth. That radiation is transmitted in packets of energy called photons.

How much photons does the sun produce?

The total solar output is around 4*10^26 W, most of which is in the visible range. A photon of visible light has an energy of around 4*10^-19 Joules. Dividing gives around 10^45 photons released by the sun per second.

How far does light travel from the sun to the Earth?

Light travels at a speed of 299,792 kilometers per second; 186,287 miles per second. It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit.

How long does it take a photon of light to make it to Earth?

eight minutes
A photon of light takes only eight minutes to get to the Earth from the surface of the Sun.

How does the Sun release photons?

The energy produced by nuclear fusion is conveyed from the heart of the Sun by light particles and heat, called photons. When merging two protons in a nucleus of deuterium to create a helium nucleus, photons are released. This particle, created in the solar core, transmits the light beam to Earth.

What part of the Sun do most of the photons that hit the Earth come from quizlet?

Most of the Sun’s energy starts in the core. It then takes hundreds of thousands of years for the energy exit as has to travel a long way to the surface. The energy goes from the core to the radiation zone as photons.

How much energy does the Earth get from the sun?

A total of 173,000 terawatts (trillions of watts) of solar energy strikes the Earth continuously. That’s more than 10,000 times the world’s total energy use. And that energy is completely renewable — at least, for the lifetime of the sun.

How many photons are emitted per second?

Dave · Stefan V. According to the equation E=n⋅h⋅ν (energy = number of photons times Planck’s constant times the frequency), if you divide the energy by Planck’s constant, you should get photons per second. Eh=n⋅ν → the term n⋅ν should have units of photons/second.

How long does it take a photon to reach the surface of the sun?

A photon of light takes only eight minutes to get to the Earth from the surface of the Sun. But it can take 100,000 years from the core of the Sun to get to the surface — where it bursts out and flies at the speed of light.
