Illustrate that the size of details of an object that can be detected with electromagnetic waves is related to their wavelength, by comparing details observable with two different types (for example, radar and visible light or infrared and X-rays).
If you wish to detect details of the size of atoms (about 11010m ) with electromagnetic radiation, it must have a wavelength of about this size. (a) What is its frequency? (b) What type of electromagnetic radiation might this be?
How does the intensity of an electromagnetic wave depend on its electric field? How does it depend on its magnetic field?
Police radar guns measure the speed of moving vehicles by transmitting electromagnetic waves at a vehicle and detecting a Doppler shift in the reflected wave. Suppose police radar transmit at a frequency of 24.0 GHz and receives a wave reflected from a car moving toward the radar at 65.0 mph. Find the frequency shift f = f0 fs between the observed (received) and source (transmitted) frequencies.
Make a list of some everyday objects and decide whether they are transparent or opaque to each of the types of electromagnetic waves.
Do Maxwells equations allow for the existence of magnetic monopoles? Explain.
