1

what can we say about a particle if it is trapped in some region by a potential

the wavelength of the particle will be quantised

2

what happens to an electron in an atom that moves down an energy level

It emits a photon of discrete energy equal to the energy difference between the original and new energy level

3

what happens to an electron in an atom that moves up in energy level

it absorbs a photon of discrete energy equal to the energy difference between the original and new energy level

4

what happens to photons that don't have any exact energy required for change in energy level

they don't interact with the system

5

what does the Hydrogen emission spectrum refer to

the wavelength of the electrons that are changing energy levels

6

what is the Bohr energy equation

E = -13.6eV / n^2

7

why is 13.6eV an important value

It is the ionisation energy of a H atom so the min energy required to move an electron from ground energy state to infinite energy state
