10.12 A monochromatic plane wave has an electric field given by Ē = (1230 î – 1640 Â ) sin(ky + 377 t) = - where t is in seconds, y is in meters, and E is in V/m. a) What is the wavenumber? b) What is the wavelength? c) What is the frequency? d) What is the maximum value of the electric field? e) At time t = 0, where along the y-axis (smallest positive coordinate) is the electric field maximum?
f) What is the wave's intensity? g) What is the wave's radiation pressure? h) What is the maximum value of the magnetic field? i) At time t = 0, where along the y-axis (smallest positive coordinate) is the magnetic field a maximum? j) In what direction does the wave travel? k) What is the magnetic field?
