What is the magnitude of this complex variable: (3 + 4i)(2 - 2i)?

Which expression is the correct evaluation of (3 + 4i)(2 - 2i), where i = ?

When the transmission from before is 1, what is the relationship between the electron’s wavelength in the well and the well width ?

Modelling a xenon atom as a one-dimensional finite square well of width 0.248 nm, estimate the kinetic energy of the electron (when inside the well) that results in maximum transmission. (Hint: expect to use your result from the first question in conjunction with equation (A.4) of the experimental script.) Give your answer in eV.

Using equation 1 from the introduction what values of  will the transmission coefficient  equal unity?

Modern society could barely function without the prior myriad of fantastic physics discoveries which have revolutionised our way of living.  Yes?

Which basis functions would be most appropriate for describing the oscillation of a string pinned at ends and ?
