determines the characteristic frequency ν < sub > 12 </ sub > of light which will interact with the atoms ; This is given by the relation

The types of signals produced by a SEM include secondary electrons, back-scattered electrons ( BSE ), characteristic X-rays, light ( cathodoluminescence ), specimen current and transmitted electrons.

The notable characteristic of stimulated emission compared to everyday light sources ( which depend on spontaneous emission ) is that the emitted photons have the same frequency, phase, polarization, and direction of propagation as the incident photons.

Maxwell's equations – the foundation of classical electromagnetism – describe light as a wave which moves with a characteristic velocity.

Ptolemy's problem is to forecast where, against the inverted bowl of night, some particular light will be found at future times.

The distances of these points of light is a problem he cannot master, beyond crude conjectures as to the orderings of the planetary orbits viewed outward from earth.

Trevelyan centers too exclusively on Bright, is insufficiently appreciative of the views of Bright's opponents and critics, and makes light of the genuine difficulties faced by Peel.

The light at that time is a benediction.

In light of the scholarly reappraisals engendered by the higher criticism this is a most remarkable statement, particularly coming from one who was well known for his antifundamentalist views.

At the left is a pair of dressy straw pumps in a light, but crisp texture.

These cases in which light is already visible at the other end of the tunnel are ones which over the next few years will absorb the bulk of our capital assistance.

A flashlight or electric lantern also should be available for those periods when a brighter light is needed.

At that time consideration will be given to whether in the light of the United States supplies of rice available for Title 1, disposal, India's production, consumption and stocks of food grains, other imports from the United States and countries friendly to the United States, India's storage capacity, and other related factors, any increase would be possible in the portion of the total rice programmed which is currently planned for procurement during the first year.

Essentially, the question presented for decision in the present Daytime Skywave proceeding is whether our decision ( in 1938-1939 ) to assign stations on the basis of daytime conditions from sunrise to sunset, is sound as a basis for AM allocations, or whether, in the light of later developments and new understanding, skywave transmission is of such significance during the hours immediately before sunset and after sunrise that this condition should be taken into account, and some stations required to afford protection to other stations during these hours.

It is a flavor that might take a little getting used to -- not because it is unpleasant, but because the flavor is hard to define in the light of our experience with other fruits.
