DAVISSON AND GERMER EXPERIMENT & De-BROGLIE’S RELATION/PHYSICS
DAVISSON AND GERMER EXPERIMENT: Davisson and Germer terminated a finely collimated light emission (beam of electrons) at the essence of the crystalline nickel target. The angular dependence of the reflected electron intensity as estimated to have a similar diffraction pattern as those anticipated by Bragg for X- ray beams. The sped up voltage is fluctuated(varied),…

HUYGENS WAVE THEORY- LAWS OF REFRACTION
WAVE THEORY: Christian Huygen, suggested the wave theory of light. Thomas Young, gave strong support to the wave theory of Christian Huygen. Fresnel, who showed that light is a transverse wave. Maxwell, on the basis of mathematical theory of magnetism showed that light is electromagnetic in nature. REFRACTION: Refraction is the phenomenon of bending of…
