Does the light of the Sun push the Earth?

The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth. If the Sun suddenly disappeared from the Universe (not that this could actually happen, don’t panic), it would take a little more than 8 minutes before you realized it was time to put on a sweater.

What force does the Sun attract the Earth?

gravitational pull
The force of this attraction—or gravitational pull—depends on the size of the objects. As the Sun is very large, it exerts a great gravitational force on Earth. The Sun’s gravitational force is like the tetherball rope, in that it constantly pulls Earth toward it.

What happens when photons reach Earth?

The photons approach the Earth’s atmosphere at the speed of light, but once they come in contact with the Earth’s atmosphere they begin to interact with gas molecules. Gas molecules absorb the photons and then instantly re-emit them.

What creates a photon?

A photon is produced whenever an electron in a higher-than-normal orbit falls back to its normal orbit. During the fall from high energy to normal energy, the electron emits a photon — a packet of energy — with very specific characteristics. A sodium vapor light energizes sodium atoms to generate photons.

What is the force of gravitational attraction between the earth and the sun?

about 3.54×1022 N
The gravitational force between the Sun and the Earth is about 3.54×1022 N. This force keeps the Earth orbiting around the Sun. The gravitational force from the other planets does slightly affect the Earth’s orbit, but the gravitational pull from the other planets and the Moon is still very small.

What is the Sun gravitational force?

274 m/s²
Sun/Gravity

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.

Can light be pushed?

Light carries momentum that can push on an object, but it can also move an object through thermal forces. This so-called optical force is used, for example, to trap glass beads in optical tweezers.

How much force does the Sun exert on the Earth?

Of course, that’s not the only force acting between the Earth and the Sun. The gravitational force of the Sun on the Earth is about 1×10 23N, which is a bit more than a hundred trillion times the radiation pressure force.

What happens to virtual photons in a magnetic field?

The virtual photons are constantly emitted and reabsorbed. A charged object with an electric (and possibly also a magnetic) field is surrounded by an entourage of photons, constantly being emitted and reabsorbed.

What is the relationship between energy and momentum of a photon?

It turns out that the photons which make up a static electric or magnetic field are “virtual” — their energy and momentum doesn’t satisfy the relationship for “real” photons — E=p*c (E is energy, p=momentum, and c is the speed of light). The virtual photons are constantly emitted and reabsorbed.

How do photons interact with each other?

They only interact with charged particles, and not with each other. That’s why photons don’t interact with magnetic fields — the photons which make up the magnetic field are not charged so other photons cannot interact with them.
