photon

What's important is that the photons have had enough time to get to you.

How does any individual photon make up its mind which way to go?

In other words, light is carried over space by photons.

But what if the photon never needs to be sent?

So all photons have energy - that is the simple part.

How does one photon "know" what the other is doing?

The photons in light cause our eyes to see certain colors.

All we do is to sense some of the photons that enter our eyes.

Brad came back with the number, a bit less than a million photons per second.

The good thing is that you are looking for photons against a dark background.

As for whether the released photon is the same, I would have to say no.

Photons can go at the speed of light because they have no mass.

You know that light is made up of particles called photons.

What does this information tell us about the properties of photons?

This energy is released in the form of a photon.

The photon can not have more energy than that which produced it.

This photon is a unit of what we call light.

A beam of light is a great many photons moving together.

Light is considered to be individual particles of energy called photons.

An individual photon must have enough energy to free the electron.

The end result would be power for just a few photon shots, but those were better than nothing.

But photons couldn't tell them everything they wanted to know.

Photons do the same thing, but for the electromagnetic force.

Thus, the time is how long it takes the energy to be transferred, not the photons themselves.

In such cases, the mass of single photons is zero.
