Photon Emission Quotes

Since we can produce all types of light by means of hot bodies, we can ascribe, to the radiation in thermal equilibrium with hot bodies, the temperature of these bodies, and thus every radiation, even that issuing from a phosphorescent body, has a certain temperature for every colour.

In this case, the particle formed has correspondingly less energy, whereas the product nucleus passes into the ground state with emission of the quantity of energy saved as gamma radiation.

The atoms become like a moth, seeking out the region of higher laser intensity.

We thought it would be nice to have atoms interact in such a gentle way with the photons that they would just take an imprint of the photons, so that many atoms could 'see' the same photon and it would give rise to a lot of interesting effects. Myself and my colleagues had this project for a very long time and we were finally able to observe it.

Light is something like raindrops each little lump of light is called a photon and if the light is all one color, all the "raindrops" are the same.

Although almost every theoretical physicist agrees with my prediction that a black hole should glow like a hot body, it would be very difficult to verify experimentally because the temperature of a macroscopic black hole is so low.

When I started on my research, I never expected I could invent the LED and laser diode.

I just think white light generation is just one of these remarkable things to see, and actually, you know, one colour of light goes in to just water or any clear anything and out comes all the colours of the rainbow when the pulses are short and intense enough.

On the basis of Lorentz's theory, if we limit ourselves to a single spectral line, it suffices to assume that each atom (or molecule) contains a single moving electron.

The emitters of the spectral series are without exception single atoms, not compounds of atoms.

There are relatively few experiments in atomic physics these days that don't involve the use of a laser.

With this in mind, for some twenty years I have set myself as my particular task the experimental investigation of the connexion between change in the structure and change in the spectra of chemical atoms.

Unfortunately, making what is essentially a laser sword falls into the deadly category.

As the craft re-entered earth's atmosphere, it was coming in so fast, it heated up the surrounding atoms and molecules, and they became positively and negatively charged, and highly reactive, and began luminescing all around us.

For her PhD, Maria Goeppert Mayer, a theoretical physicist, came up with the idea of multi-photon physics. That means an atom absorbs two or more photons simultaneously.

In my view the structure of the whole atom was that of an individual, with all its parts interconnected, and the emission of a spectral line appeared to me to be the result of the coherence and co-operation of several electric quanta.

If we have an atom that is in an excited state and so is going to emit a photon, we cannot say when it will emit the photon. It has a certain amplitude to emit the photon at any time, and we can predict only a probability for emission; we cannot predict the future exactly.

Photons have neither morals or visas.

Spectroscopy can probably answer the question, 'Is there anybody out there?' Are we alone?

Only black holes of very low mass would emit a significant amount of radiation.
