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…

INTERFERENCE OF LIGHT/PHYSICS
INTERFERENCE OF LIGHT: The phenomenon by which intensity is redistributed when two light waves from two coherent sources superpose each other. *INTERFERENCE OF LIGHT is an example for the Wave nature of light. *CONSTRUCTIVE : When the two waves are in phase. *DESTRUCTIVE: When the to waves are out of phase. COHERENT SOURCES: S1 and…

NEET PHYSICS-QUESTION ANSWER & SOLUTION (7)
QUESTION-1 The wave nature of electrons was experimentally verified by [A] Hertz [B] Einstein [C] Davisson and Germer [D] de Broglie ANSWER : ANSWER:[C] SOLUTION: From de Broglie hypothesis,the wavelength associated with an electron beam accelerated through 54 V should be 1.66 X 10-10 m. The tentatively estimated wavelength is near that assessed…
