Why do photons take so long to reach the surface of the Sun?

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.

How long does it take for a photon to reach the Sun’s surface?

However, before exiting our star, each photon must first undergo a long journey. Over the course of 40,000 years it will be absorbed by other atoms and emitted repeatedly until reaching the sun’s surface. Once there, the photons stream out, illuminating Earth, the solar system and beyond.

How long does it take photons to move through it?

Traveling at the speed of light, photons emitted by the Sun take a little over eight minutes to reach the Earth.

How does energy transport from the center of the Sun to the surface of the Sun?

Fusion of hydrogen occurs in the center of the Sun, and the energy generated is carried to the surface by radiation and then convection.

How long does a photon live?

Photons Last At Least One Quintillion Years, New Study Of Light Particles Suggests. The particles that make up light, photons, may live for at least 1 quintillion (1 billion multiplied by 1 billion) years, new research suggests. If photons can die, they could give off particles that travel faster than light.

How long does it take a photon to pass through the radiative zone?

50 million years
Particles of light called photons can only travel a few millimeters before they hit another particle in the Sun, are absorbed and then released again. It can take a photon as long as 50 million years to travel all the way through the radiative zone.

How long does it take a photon of light to escape the Sun?

Very approximately, this means that to travel the radius of the Sun, a photon will have to take (696,000 kilometers/1 centimeter)^2 = 5 x 10^21 steps. This will take, 5×10^21 x 3 x10^-11 = 1.5 x 10^11 seconds or since there are 3.1 x 10^7 seconds in a year, you get about 4,000 years.

How long is a photon?

So excluding space everything has mass & hence also has size and hence photon also has size. , 400 n m–700 n m=(4–7) X 10^-9 meter,which means photon can be in any wave length depending on its energy,which a gain means no specific size to photon. You can’t think of photons as a tiny spherical particle.

Why couldnt you stand on the Sun surface?

Why couldn’t you stand on the Sun’s surface? The Sun doesn’t have a solid surface.

How energy given off by the Sun varies over time?

Over the course of one solar cycle (one 11-year period), the Sun’s emitted energy varies on average at about 0.1 percent. That may not sound like a lot, but the Sun emits a large amount of energy – 1,361 watts per square meter. Even fluctuations at just a tenth of a percent can affect Earth.
