11. The electric and magnetic fields of an EM wave moving through free space at an instant in time are given by the expressions: N E = (80.0â + 32.0ŷ – 64.02) B = (0.200âx + 0.080ŷ + 0.290£) µT a) Show that the two fields are perpendicular to each other.

A fine metal foil separates one end of two pieces ofoptically flat glass, as in Fig. 24–33. When light of wavelength 670 nm is incident normally, 24 dark bands areobserved (with one at each end). How thick is the foil?
b) Waveplates formed from accurate thicknesses of birefringent material may be used to change the polarisation state of light. For each of the following configurations of incident light (travelling horizontally), linear polarisers and waveplates, describe the polarisation state of the transmitted light: (i) Unpolarised light incident on a linear polariser with transmission axis vertical, followed by a half-wave plate with o and e axes at ±45 degrees to the vertical. (ii) As (i) above, but the half-wave plate is replaced by a quarter-wave plate at the same orientation (iii) As (i) above, but the linear polariser is rotated with axis at 30 degrees from the vertical, then the half-wave plate. (iv) As (i) above, but the half-wave plate is rotated with o axis vertical and e axis horizontal.
3. Electromagnetic waves from a radio station pass through an open window of a house. The square window has side length 0.75 m and the waves pass through perpendicular to the window's area. The electric field is measured at the window and found to be 0.02 V/m. In air, we can use the vacuum permeability = 4 x 10-7 H/m. (i) What is the magnitude of the Poynting vector, S, for the radio waves passing through the window? (ii) How much energy do the radio waves carry through the window during a 2-minute-long broadcast of BBC Radio 4's shipping forecast? [Hint: think of the units of S [units = (J/s)/m²] and Energy [units = J].
The ratio If/lo is maximized when polarizer X is rotated so its polarization axis is 45° different from that of polarizer A (that is, when OAx is 45°). What is this maximum intensity ratio?
