Sentences with phrase «sufficient number of these photons»

If a sufficient number of these photons can be measured with a detector, a characteristic diffraction pattern is obtained which can be used to derive the pattern of scattered atoms or the crystal structure.

Not exact matches

So to argue for the insignificance of the thermosphere to radiative balance it is not sufficient to point to its small mass and number of molecules — one must accompany this with physics showing for instance the mean free path of photons between interactions with air molecules to be sufficiently long that the thermosphere will not significantly affect outgoing flux.
