- Question A2 Red light of vacuum wavelength 650 nm is travelling in a non-magnetic dielectric glass of refrac- tive index ng = 1.60. Calculate the impedance of the glass, the wavelength of light in the glass, and the critical angle 0c for total internal reflection at a glass-air interface. Question A3 Light is incident from air onto a horizontal surface of water of refractive index nw = 1.33. Calculate the Brewster angle at which the reflectance for the TM polarisation is zero. Also, cal- culate the power reflection coefficient RTE for TE-polarised light incident at this Brewster angle.Prior to the switch to digital television broadcasting, and to the popularity of cable television, many homes had outdoor TV antennas. TV-reception antennas for VHF (channels 2 through 13) were constructed with cross wires supported at their centers, as shown in the figure below. The ideal length for the cross wires is one-half the wavelength to be received, with the more expensive antennas having one for each channel. Suppose you measure the lengths of the wires for channels 12 and 6 and find them to be 0.208 m and 0.958 m long, respectively. What is the frequency for channel 12?Hz What is the frequency for channel 6?Hz1
