Consider the blackbody radiation emitted at a temperature of
500◦C.
(i) Explain why a tungsten wire in an old-fashioned light-bulb starts
to glow as it becomes sufficiently hot.

(ii) Calculate the percentage pressure increase of the blackbody
radiation if the temperature is raised to 550◦C.

An electron escapes the hot tungsten wire and is subsequently
trapped in a one-dimensional square quantum well. The potential
outside the well can be approximated as infinite.

(iii) Sketch the probability distribution of the electron within the
square well for the n = 2 quantum state.

(iv) The electron energy for the n = 2 state is 10.0 eV. Calculate the
width of the well.
