Radiation definition: the process in which energy is emitted as particles or waves.. See examples of RADIATION used in a sentence.
Noble gases have an octet (i.e. group of eight) of electrons in their valence shells, meaning that the tendency of an atom to gain or to lose its valence electrons to form ions in the noble gas arrangement is called the “octet rule.”7 Chemical species of atoms are particularly stable...
It is used to detect corneal abrasions and to evaluate the fit of hard contact lenses. It is available in a slit-lamp or in a Burton lamp. See fluorescein; fluorescence; Burton lamp. Millodot: Dictionary of Optometry and Visual Science, 7th edition. © 2009 Butterworth-Heinemann...
natural action,natural process,action,activity- a process existing in or produced by nature (rather than by the intent of human beings); "the action of natural forces"; "volcanic activity" 3. scattering- a light shower that falls in some locations and not others nearby ...
It’s a lot of fun to refer to your special someone by a nickname or pet name. If you love endearing terms as much as we do, then you’ll fall in love with this quiz. Question 1 of 12 The word BEAU comes through ___ from the Latin bellus, meaning “beautiful.” Italian...
For an in-depth look at the meaning of the temperature of radiation, consult the work of Petela 2010 [34]. The total energy of the radiation in volume V is (2.71)U=uV=aT4V The blackbody radiation contained inside the cavity exerts a pressure on its walls. Both from Classic ...
When you use sound with this meaning, don't say 'the sound'. Don't use expressions such as 'much' or 'a lot of' with sound. Don't say, for example, 'There was a lot of sound'. Say 'There was a lot of noise'. Is that the wind making all that noise? Try not to make so...
brain or the ear is greater, meaning that the greater the distance, the strength of radiation will decrease exponentially. legco.gov.hk 在其他範疇,我們知道這些輻射場是有距離的因素,即是如果手 機與腦部或耳朵的距離越遠,便會形成inverse square,即距離越遠, 所受輻射便會以倍數遞減。 legco.gov....
Through these interactions VHE gamma rays are converted into electron–positron pairs, meaning that they have finite energy-dependent mean free paths. This results in a cosmic gamma-ray horizon at a redshift of about z=1 at E∼100GeV. Though this could be seen as a fallback for gamma ...
This deflection causes a deceleration of the beta particle and consequently a reduction in its kinetic energy with the emission of energy as a photon of bremsstrahlung, which is taken from the German meaning “braking radiation.” The phenomenon is described by: Sign in to download full-size ...
