Chapter 34, Problem 77

(choose chapter or problem)

A linearly polarized microwave of wavelength 1.50 cm is directed along the positive \(x\) axis. The electric field vector has a maximum value of 175 V/m and vibrates in the \(xy\) plane. Assuming the magnetic field component of the wave can be written in the form \(B=B_{\max}\ \sin\ (kx-\omega t)\), give values for (a) \(B_{\max}\), (b) \(k\), and (c) \(\omega\). (d) Determine in which plane the magnetic field vector vibrates. (e) Calculate the average value of the Poynting vector for this wave. (f) If this wave were directed at normal incidence onto a perfectly reflecting sheet, what radiation pressure would it exert? (g) What acceleration would be imparted to a 500-g sheet (perfectly reflecting and at normal incidence) with dimensions of \(1.00 \mathrm{~m} \times 0.750 \mathrm{~m}\)?
