WebNov 5, 2024 · Electromagnetic radiation applies radiation pressure equal to the Intensity (of light beam) divided by c (speed of light). Laser cooling uses radiation pressure to remove energy from atomic gases. The technique can produce cold samples of gases at 1mK or so. http://hyperphysics.phy-astr.gsu.edu/hbase/Waves/emwv.html
WebThe speed of propagation vw is the distance the wave travels in a given time, which is one wavelength in a time of one period. In equation form, it is written as v w = λ T 13.3 or v w = f λ. 13.4 From this relationship, we see that in a medium where vw is constant, the higher the frequency, the smaller the wavelength. See Figure 13.8. http://electron9.phys.utk.edu/optics421/modules/m1/emwaves.htm
