Question 10
The statements in the following list all refer to QuantumPhysics. Check the boxes of the THREE CORRECT statements.
1. In the photoelectric effect, the maximum energy of theemitted electrons depends on the frequency of the incomingelectromagnetic radiation and not on the intensity. There is athreshold frequency below which no electrons are emitted.
2. Electrons can behave both as particles and as waves.
3. It is not necessary to know the potential energy function ofa particle in order to to solve the time-independent Schrödingerequation and obtain the wave function describing it.
4. The allowed energy levels of a particle in an infinite squarewell are equally spaced.
5. In spectroscopic notation, the letters 's', 'p', 'd', etc.are used to identify the magnetic quantum numberml associated to a state or energylevel.
6. An atom can be stimulated to make a transition from a higherto a lower energy level by a photon of the appropriate energy.
