We should note that this latter type of shift was successfully amplified to a considerable extent by Russian physicists using the intense light of a ruby laser whose wavelength is close to that of a transition of the potassium atom.

I was very eager to produce an oscillator for short waves. I was doing science with microwaves, and I would get down to a few millimetres in wavelength, but I wanted to get shorter wavelengths; I wanted to get into the infra-red because I saw there was a lot more to be done there.

In general, the objects in the universe that are very high-energy objects, or the processes that are high-energy processes, will radiate more in the short wavelength range towards the gamma rays or the x-rays.

During exposure, interference takes place between the incident rays and those reflected by the mirror, with the formation of interference fringes half a wavelength distant from each other.

It's awkward going back up to Edinburgh to see my old friends, because I'm not on the same wavelength.

Along a series of lines running from longer to shorter wavelengths the effect of the electric field becomes greater as the serial numbers increase - that is, as the wavelength decreases.

The electron can no longer be conceived as a single, small granule of electricity; it must be associated with a wave, and this wave is no myth; its wavelength can be measured and its interferences predicted.

For X-rays, the phenomenon of diffraction by crystals was a natural consequence of the idea that X-rays are waves analogous to light and differ from it only by having a smaller wavelength.

A lot of men are very possessive and they want to control you. But as you grow older, you attract people who are on your wavelength and who understand who you are.
