Scientists are working on a new technique to kill cancer cells by zapping them
with ultrahigh-energy (in the range of 1.00×1012 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 5.00 μm in diameter, with the pulse lasting
for 4.00 ns with an average power of 2.00×1012 W. We shall assume that the
energy is spread uniformly over the faces of 100 cells for each pulse.

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?
You have been hired as an expert witness for an attorney who is representing a speeding driver. The driver of the car was given a ticket for running a red light at an intersection. According to the driver, who has taken some courses in physics, when he was looking at the red light as he approached the intersection, the Doppler shift made the light of wavelength 650 nm appear to be green light of wavelength 520 nm. Therefore, according to the driver, he should not be charged with running a red light because it appeared green to him. What advice do you give the attorney?

- When high-energy charged particles move through a transparent medium with a speed greater than the speed of light in that medium, a shock wave, or bow wave, of light is produced. This phenomenon is called the Cerenkov effect. When a nuclear reactor is shielded by a large pool of water, Cerenkov radiation can be seen as a blue glow in the vicinity of the reactor core due to high-speed electrons moving through the water as shown. In a particular case, the Cerenkov radiation produces a wave front with an apex half-angle of 53.0°. Calculate the speed of the electrons in the water.
