Which of the following wavelengths could be used to measure the position of an electron with the greatest accuracy?
Which of the following wavelengths could be used to measure the position of an electron with the greatest accuracy?
The Heisenberg Uncertainty principle states that
Therefore, the smallest wavelength will have the lowest uncertainty in the position. Thus, we must pick the regime of options given which has the lowest wavelength. That is gamma-ray.

What wavelength will result in the most accurate measurement of the momentum of an electron?
What wavelength will result in the most accurate measurement of the momentum of an electron?
The Heisenberg Uncertainty Principle states that:
Since the uncertainty in the position is inversely proportional to the uncertainty in the momentum, we need to pick the longest wavelength. Of the options listed, radio has the longest wavelength.

If a ground state particle is in a one-dimension square well, where is the probability of finding the particle equal to zero?
If a ground state particle is in a one-dimension square well, where is the probability of finding the particle equal to zero?
This is a fundamental concept question. For a ground state particle, the only place where the probability is equal to zero is at the boundary because the particle cannot be found there. He has to be in the box (not unlike a cat).

What is the energy of the photon emitted when a Hydrogen atom makes a transition from the 
to the 
atomic energy level?
What is the energy of the photon emitted when a Hydrogen atom makes a transition from the
, where 
refers to the final and initial energy levels, respectively.
However, since the question asked what is the energy of the photon, it is the absolute value of the energy calculated above because of conservation of energy. The photon carries away the energy lost by the atom.
