Let's try a few examples of relating wavelength, frequency, and wave speed. You might want to review SI prefixes. For example, kilo (k) means 1,000, mega (M) means 106, milli (m) means 103, and nano (n) means 10-⁹. In the U.S., FM radio stations broadcast with frequencies within a band from 88.0 to 108.0 MHz. What is the wavelength (in m) of a radio wave emitted from an FM radio tower with a frequency of 99.7 MHz? m Visible light that is perceived as green in color by most human eyes have wavelengths from 520 nm to 560 nm. What is the frequency (in Hz) of green light with a wavelength of 532 nm? Hz X-rays with wavelength of about 0.1 to 0.2 nm are used in medical imaging. (This is approximately the same length as the diameter of a typical atom.) What is the frequency (in Hz) of an x-ray with a wavelength of 0.157 nm? Hz

Radio station WWVB, operated by the National Institute of Standards and Technology (NIST) from Fort Collins, Colorado, at a low frequency of 60 kHz, broadcasts a time synchronization signal whose range covers the entire continental US. The timing of the synchronization signal is controlled by a set of atomic clocks to an accuracy of 101012 s, and repeats every 1 minute. The signal is used for devices, such as radio-controlled watches, that automatically synchronize with it at preset local times. WWVB's long wavelength signal tends to propagate close to the ground. (a) Calculate the wavelength of the radio waves from WWVB. (b) Estimate the error that the travel time of the signal causes in synchronizing a radio controlled watch in Norfolk, Virginia, which is 1570 mi (2527 km) from Fort Collins, Colorado.
