Webb1 jan. 2016 · Rayleigh treated the scattering of light by a spherical particle, whose diameter is much smaller than that of the wavelength of light. It is generally accepted that this size regime applies for particles (or molecules) of size less than 1/10th the vacuum wavelength, λ, of the incident light.Rayleigh considered a plane wave incident on a dielectric sphere … Webb18 okt. 2024 · This textbook was considered the standard work on the subject for many years and provided the foundations of modern acoustic theory.

WebbA conflict or a difference between theory and observation is termed as an ultraviolet catastrophe in physics. The Rayleigh-Jeans law led to an ultraviolet catastrophe. The law predicted that the brightness of black bodies would keep increasing at higher radiation frequencies, and the total power that the body would radiate per unit area would be infinite.
