Rayleigh-jeans law equation

Web2.5 Rayleigh Jean’s Distribution Law Lord Rayleigh and J. H. Jeans developed an equation which explained black-body radiation at low frequencies. The equation which seemed to … 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.
