Sentences with phrase «quantum mechanical effect of»

If you accept diurnal variation as a proxy for net absorption, since the quantum mechanical effect of absorption is to heat the air, then you can see from Fig. 2 that most of the net absorption occurs below 850 mb and that above 500 mb the tiny amount of net absorption slowly increases showing that it is the result of the absorption of solar not terrestrial radiation.

Nuclear theorists believe that the combined quantum mechanical effect of the protons and neutrons in a nucleus create a set of energy levels akin to the levels that govern electrons orbiting the nucleus.

Two examples: graphene — single - atom - thick sheets of carbon atoms — has unique mechanical, electrical, and optical properties; and two - dimensional electron gases (2DEG)-- planar collections of electrons supported at the interface between certain semiconductors such as gallium arsenide — allow the observation of such emergent behaviors as the quantum Hall effect and the spin Hall effect.

Many scientists had attributed its light - emitting properties to quantum mechanical effects created by the multitude of tiny columns left by the etching.
