How much energy will the sun release in its lifetime?

We therefore can calculate that the total energy the sun has to burn is around 1.3 x 1044 Joules. Dividing 3.8 x 1026 Watts (the rate at which the sun is giving off energy) into this number gives an approximate value of 10 billion years for the sun’s lifetime.

How many photons does the sun produce per second?

1,383,279,502,884,197,169,399,375,105,820,974,944,592,307,816 photons/s.

Does sun emit photons?

Deep in the sun’s fiery core, atoms fuse and create light. An elegant interaction powers the sun, producing the light and energy that makes life possible. This process often leads to the creation of a photon, the particles of light that are released from the sun.

How long do photons take to get out 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.

What are 2 quantities that affect the lifetime of the sun?

If the star masses and luminosity are in units relative to the Sun, then the star’s lifetime = mass/luminosity × 1010 years. Recall that the Sun’s will live for ten billion (1010) years before it runs out of hydrogen in its core.

How many volts does the sun produce?

Solar Panels The solar cells are able to convert more than 26 percent of the Sun’s energy directly into electricity (that’s very good for solar cells!), and are connected together so that the power they produce is 32 volts, the voltage that most devices on the spacecraft need to operate properly.

At what rate does the Sun emit photons?

1.0×1045Photons/s.

What is the sun really made up if not gas?

It does not have easily identifiable boundaries like rocky planets like Earth. Instead, the sun is composed of layers made up almost entirely of hydrogen and helium. These gases carry out different functions in each layer, and the sun’s layers are measured by their percentage of the sun’s total radius.

How fast does a photon travel?

The theory of special relativity showed that particles of light, photons, travel through a vacuum at a constant pace of 670,616,629 miles per hour — a speed that’s immensely difficult to achieve and impossible to surpass in that environment.

How many photons does Sunsun emit per second?

Sun is roughly typical star and emits about photon per second in the visible range. It takes about 100 photon incident on the pupil, of ]

How long does it take a photon to travel through the Sun?

To send us this photon must traverse the various layers of the Sun. The transit time of a photon of the heart at the surface is between 10 000 and 170 000 years based on collisions.

How do you calculate the amount of energy a photon has?

We know the average wavelength of a photon coming from the sun, and with the wavelength you can calculate the amount of energy a single photon has. You divide the total amount of energy the sun gives off in a second by the average energy of a photon and you have the total number of photons the sun gives off every second.

How many photons does a star emit in a second?

The equation for the surface are of a sphere is A=4πR^2. In our case the radius R is 16,300 light years (which is about 1.5*10^20 meters). So the star must emit at least (4π (1.5*10^20)^2)*1000 or about 3*10^44 photons per second.
