Date of Issue:01/10/2024 Last Date of Submission:08/10/2024 Marks: 25 Q# Question Description CO BTL MM Write down Planck’s radiation formula and show that Wien’s law and 1 Rayleigh Jeans law can be obtained as special case of Planck’s radiation CO1 K2 5 formula. Distinguish between group velocity and phase velocity. Establish a 2 relation between them in a dispersive medium. What will be the relation CO1 K2 5 between these velocities in non dispersive medium? Write down the time independent Schrodinger equation for a particle in 3 one-dimensional box (infinitely deep potential well) and find out energy CO1 K3 5 eigen values (energy levels) and the corresponding energy eigen functions (normalized wave functions) of the particle A particle moving in one dimensional box is described by the wave function. 4 Ψ = x√2 for 0 ˂ x ˂ 1 and CO1 K3 5 = 0 for x ≤ 0 and x ≥ 1. Find the probability of finding the particle within the interval (0, 1/2). Derive an expression for Compton wavelength. Calculate the Compton 5 shift and kinetic energy of recoil electron if X-rays of wavelength 1.0 Å are CO1 K3 5 scattered form a carbon block. The scattered radiation is viewed at 900 to the incident beam. Name of Faculty: Dr. Shiv Singh BBDNIIT 2024-25(Odd Semester) Page1
