What is black body radiation? What is Wein's Law? What is Rayleigh Jeans law? What is plank's radiation? Plank radiation of black body radiation Plank's radiation formula. Plank's radiation formula in terms of frequency Plank's radiation formula in terms of wavelength What is dual nature of particle? What is de-broglie hypothesis? What is De-broglie concept? De-Broglie wavelength Properties of matter wave wavelength Properties of de-broglie wavelength Phase velocity Group velocity What is phase and group velocity? Q1 State Wien’s displacement law and Rayleigh-Jeans law. Q2 Why are matter waves associated with a particle generated only when it is in motion? Q4 Why is black the best emitter? What is de-Broglie hypothesis? Q7 Write the assumptions of Planck’s hypothesis. Q12 What is the Planck’s theory of black body radiations? Obtain an expression for the average energy of the oscillators and derive the Planck’s radiation law. Q20 Derive Planck’s law of radiation. How does it explain Wien’s displacement and Rayleigh-Jeans laws? #EngineersGateWay #gateway #physics #engineeringphysics #technical #B.Tech #engineering #trending #virul #video #digitalelectronics #Digitalsysytemdesign #communication #wireless #analogcommunication #digitalcommunication #cse #ece #civil #mechanicalengineering #engineering #ksvira #1stsem #2ndsem #3rdsem #4thsem #AKTUvirul Er.
