Heisenberg uncertainty relation holds good for microscopic as well as macroscopic particles both only microscopic particles only macroscopic particles none of these Quantum mechanically when you measure the position accurately, you will observe uncertainty in momentum. While one measure the momentum exactly uncertainty comes in position. The product of these two uncertainties is equal to hbar. 2. The energy of a particle in an infinite potential well is proportional to n^2 inversely proportional to n^2 proportional to n inversely proportional to n “Particle in a box or in an infinite potential well” this statement is a representation of a physical problem. As you know in a conductor for the current flow of free electrons are responsible. You know these free electrons doesn’t escape from the conductor surfaces. It means they are bound with in the boundary of material. The surfaces of conductor is treated as high potential walls. Particle that is electron is free to move inside the conductor. 3. Which of the following relation is not true according to uncertainties principle ΔEΔt = ħ ΔEΔt= h/2п ΔxΔpx = ħ ΔxΔpy = ħ 4. The momentum of a photon is given by relation P=E/c P=hν/c zero Both (a) & (b) 5. The equation of motion of matter wave is given by Heisenberg Schrodinger Bohr de Broglie 6. The de Broglie wavelength of a material particle depends on velocity energy momentum All of the above Loading … Tags #Quiz Research & Publications Digital Farming Content and Social Media Science Magnetic Hysteresis Loop and B H Curve Explanation Related posts Class Notes Cathode Ray Tube (CRT) Construction and Working Dr Sushil Kumar, 08/12/2017 4 min read Class Notes How to find Normalization Constant of a Wave Function & Physical Meaning Dr Sushil Kumar, 29/01/2017 1 min read Class Notes What is Voltage Source in Electric Circuits?
