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.
A highway patrol officer uses a device that measures the speed of vehicles by bouncing radar off them and measuring the Doppler shift. The outgoing radar has a frequency of 100 GHz and the returning echo has a frequency 15.0 kHz higher. What is the velocity of the vehicle? Note that there are two Doppler shifts in echoes. Be certain not to round off until the end of the problem, because the effect is small.

Select one: a. 2.2 kHz (higher frequency) o b. 2.2 kHz (lower frequency) c. 4.8 kHz (higher frequency) o d. 4.8 kHz (lower frequency)
High-Energy Cancer Treatment. Scientists are working on a new technique to kill cancer cells by zapping them with ultrahighenergy (in the range of 1012 W) pulses of light that last for an extremely short time (a few nanoseconds). These short pulses scramble the interior of a cell without causing it to explode, as long pulses would do. We can model a typical such cell as a disk 5.0 um in diameter, with the pulse lasting for 4.0 ns with an average power of 2.0 * 1012 W. We shall assume that the energy is spread uniformly over the faces of 100 cells for each pulse. (a) How much energy is given to the cell during this pulse? (b) What is the intensity (in W/m2) delivered to the cell? (c) What are the maximum values of the electric and magnetic fields in the pulse?

A fighter jet moving at constant velocity of 200 m/s is being chase by an enemy jet 500m away with also a constant velocity. The radar transmitting 1 MHz broke its display from the last fight but still working. The returned frequency from the radar is 1.0000002 MHz. How long it will take for the chasing jet to reach the first jet?
A police car’s radar gun emits microwaves with a frequency of f1 = 8.70 GHz. The beam reflects from a speeding car, which is moving toward the police car at 44.5 m/s with respect to the police car. The speeder’s radar detector detects the microwave at a frequency f2. Find the frequency difference (in kHz) f2 − f1.
Assume that when I was 30 years old, I invented a spaceship capable of traveling at 95% of the speed of light, and take off to survey a peculiar infrared star 10 light years from earth. My daughter is 2 years old when I leave earth. I calculate that I age 20 years on my mission. A. while traveling to the star at 95% of the speed of light, I measure the wavelength of its light at 450 nm. What is the actual wavelength of the star's light? B. I turn around and head back to earth at 95% of the speed of light. WHat is the wavelength I see and I move away from the star? C. From my daughter prespective, how old is she when I return?
