Show that at long wavelengths, Planck’s radiation law reduces to the Rayleigh-Jeans law. SOLUTION for small x, therefore, -> Rayleigh-Jeans law Show that if the total energy of a moving particle greatly exceeds its rest energy, its de Broglie wavelength is nearly the same as the wavelength of a photon with the same total energy. What is the photon's de Broglie wavelength?

Physics 2056 Assignment # 2W Due: 11 March 2003. Show that at long wavelengths, Planck’s radiation law reduces to the Rayleigh-Jeans law. SOLUTION for small x, therefore, -> Rayleigh-Jeans law Show that if the total energy of a moving particle greatly exceeds its rest energy, its de Broglie wavelength is nearly the same as the wavelength of a photon with the same total energy.

v = 2eV / rt(m) The de Broglie wavelength is De Broglie wavelength. The wavelength γ = h/p associated with a beam of particles (or with a single particle) of momentum p; h = 6.626 × 10 34 joule-second is Planck's constant. The same formula gives the momentum of an individual photon associated with a light wave of wavelength γ. Se hela listan på physicsabout.com Formula : λ = h / (m×v) Where, λ = Wave length h = Plank's Constant (6.62607 x 10 -34 ) m = Mass v = Frequency Calculation of De Broglie Wavelength of Particle is made easier the energy of a debroglie wave can be gotten from the equation below E=hv/2l where l=wavelength it is obvious that a change in velocity will lead to a change in wavelength and energy. Therefore E=f(v,l) Using partial derivatives, the change in energy, dE is expressed through the following equation. dE=h/2l(dv.(v/l).dl) En 1924, el joven físico teórico francés Louis de Broglie introdujo el concepto de las olas de materia en la circulación científica. Esta atrevida suposición teórica extendió la propiedad de la dualidad onda-partícula (dualidad) a todas las manifestaciones de la materia, no solo a la radiación, sino también a cualquier partícula de la materia.
