Photon Energy Quotes

All the fifty years of conscious brooding have brought me no closer to answer the question, "What are light quanta?" Of course today every rascal thinks he knows the answer, but he is deluding himself.

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.

The bubbles are thinner than wavelengths of light.

I look at light as a material. It is physical. It is photons. Yes, it exhibits wave behavior, but it is a thing.

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

The speed of light sucks.

A beam of luminous hydrogen canal rays has, owing to its velocity, exactly the same direction as that of the electric field in which it may be made to move.

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

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

The process of radiation may be, and is, continuous - at any rate within limits extending to far smaller quantities than the quantum.
