In which situation shown in Figure\({\rm{24}}{\rm{.24}}\)will the electromagnetic wave be more successful in inducing a current in the wire? Explain.
Make a list of some everyday objects and decide whether they are transparent or opaque to each of the types of electromagnetic waves.
The direction of the electric field shown in each part of the Figure 24.5is that produced by the charge distribution in the wire. Justify the direction shown in each part, using the Coulomb force law and the definition of E=F/q, where qis a positive test charge.
Figure 24.26 shows the interference pattern of two radio antennas broadcasting the same signal. Explain how this is analogous to the interference pattern for sound produced by two speakers. Could this be used to make a directional antenna system that broadcasts preferentially in certain directions? Explain
(a) What is the wavelength of 100 MHz radio waves used in an MRI unit? (b) If the frequencies are swept over a range centered on 100MHz , what is the range of wavelengths broadcast?
