Rayleigh-jeans law equation
WebRayleigh-Jean’s law holds good for which of the following? a) Shorter wavelength b) Longer wavelength c) High temperature ... This equation shows that the change in wavelength is independent of the incident radiation as well as the nature of scattering substance. The shift depends only on the angle of scattering. WebJan 16, 2014 · The energy density (i.e., the energy per unit volume) is therefore given by a relation known as Rayleigh-Jeans' law. The expression is valid for but incorrect for , as it predicts that in this case the energy density should become infinite. This physically incorrect property of the equation would lead to what has been termed “UV catastrophy". 16.
