Around the core of a nuclear reactor shielded by a large pool of water, Cerenkov radiation appears as a blue glow (see figure below). Cerenkov radiation occurs when a particle travels faster through a medium than the speed of light in that medium. It is the electromagnetic equivalent of a bow wave or a sonic boom. An electron is traveling through water at a speed 9.2% faster than the speed of light in water (a) Determine the electron's total energy. MeV (b) Determine the electron's kinetic energy. MeV (c) Determine the electron's momentum. MeV/c (d) Find the angle between the shock wave and the electron's direction of motion.

Step 1
The mass of an electron is approximately 9.11 x 10^-31 kg, and the speed of light is approximately 3.00 x 10^8 m/s. Plugging these values into the equation, we get: E = (9.11 x 10^-31 kg)(3.00 x 10^8 m/s)^2 E ≈ 8.20 x 10^-14 J To convert this energy to MeV, we can Show more…

A gamma-ray photon of energy 800 keV scatters off an electron at an angle perpendicular to its original direction. It then scatters off a second electron such that this secondary scattered photon continues in the direction of the original photon. Calculate the difference in energy between the first and second recoiling electrons.
