TV-reception antennas for VHF (channels 2 through 13) are constructed with cross wires supported at their centers, as shown in Figure 23.24. 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 4 and 3 and find them to be 2.23 and 2.45 m long, respectively.

What is the frequency for channel 4?

What is the frequency for channel 3?
