Light of wavelength 675 nm passes through a double slit, and makes its
first minimum (m = 1) at an angle of
0.111 deg. What is the separation of
the slits, d, in MILLIMETERS?
(Remember, milli means 10-3.)
(Unit = mm)
Make sure your calculator is in DEG and not RAD mode!

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
