An electron is bound in a square well of depth. What is the width of the well if its ground state energy is?
Short Answer
The width of the well is, if its ground state energy is.

In classical (Newtonian) mechanics, the total energy E of a particle can never be less than the potential energy U because the kinetic energy K cannot be negative. Yet in barrier tunneling a particle passes through regions where E is less than U. Is this a contradiction? Explain.
In a photoelectric-effect experiment, which of the following will increase the maximum kinetic energy of the photoelectrons? (a) Use light of greater intensity; (b) use light of higher frequency; (c) use light of longer wavelength; (d) use a metal surface with a larger work function. In each case justify your answer.
In what ways do atoms in a diatomic molecule behave as though they were held together by a spring? In what ways is this a poor description of the interaction between the atoms?
During the photoelectric effect, light knocks electrons outof metals. So why don’t the metals in your home lose their electrons when you turn on the lights?
