Quantum Conceptual Analysis Homework. For each statement, decide whether it is always true, always false or true in certain circumstances. State which case applies to the statement, describing why you chose the answer you did and cite an experiment or principle of Physics which supports' your claim. t) The momentum of an individual photon is proportional to its wavelength. 2] A beam of particles passing through a double slits will produce an interference pattern This means that each particle passes through one slit or the other [3] The orbitals in an atom are just regions where the electron has a high probability of being found and are static in time. [4] Quanta can have angular momentum only if they are moving in some kind of orbit. [5] Momentum, angular momentum, energy and electric charge are all conserved in quantum mechanics. [6] If no measurement of a particle's position or energy is made, there will be no uncertainty in its momentum or half-life. 17] Particles with mass can never be in more than one location at the same time. 7] Particles with

Explanation / Answer

a) False

The momentum of the photon is p = hbar k = h/lambda

i.e. the momentum is inversely proportional to the wavelength.

b) False

The interference fringes are due to the wave nature of the particles existing because of their small size. Here, the probabilities gets interfere rather than the particles.

c) true

The orbitals are static in time and the electrons can be found only in orbitals except for metals.
