How long does it take for a photon to leave the Sun?

How long does it take for a photon to leave the Sun?

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

How long does it take for a light photon to leave the Sun and arrive at Earth?

8 minutes and 20 seconds
Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.

Why does it take thousands of years for energy at the Sun’s core to reach the Suns surface?

Unlike a neutrino, which slips out untouched at almost the speed of light. It is in fact a way of saying that the Sun has relatively low thermal conductivity and is half a million miles in radius. It therefore takes a long time for a change in energy production at the core to be felt at the surface.

Why does it take 20000 years for light to reach the surface of the sun from its core but just 8 minutes to reach the surface of the Earth?

You know that photons are created by fusion reactions inside the Sun. Actually photon takes 20,000 years to travel from the core of the sun to its surface. Once they escaped the surface, it takes only 8 minutes for those photons to cross the vast distance from the Sun to the Earth.

How long does it take for a neutrino to escape the Sun?

With a radius of approximately 432,000 miles (~700,000 km), neutrinos take less than three seconds to exit the Sun from the time they are produced. Despite moving slower than photons, neutrinos barely interact with matter, streaming out at approximately c.

How fast are photon beams?

Photons are massless, so they always move at the speed of light in vacuum, 299792458 m/s (or about 186,282 mi/s).

Why does it take photons so long to leave the Sun?

Collisions. In the core of the sun the protons and helium nuclei are so thick that an emitted gamma ray can’t get very far before it is absorbed. If you imagine that a gamma ray is emitted right at the center of the sun then it will start out heading right for the surface.

How long does it take energy from the Sun to reach Earth?

The Sun is 93 million miles away, so sunlight takes 8 and 1/3 minutes to get to us.
