The AMANDA neutrino telescope

10) The AMANDA neutrino telescope was mentioned in Reference below. The neutrinos it detects have passed through the earth and are rising through the ice sheet. There are an enormous number of neutrinos doing this every second. A tiny proportion of these interact with quarks within protons or neutrons in the ice to form muons. There are three generations of neutrino, state which kind of neutrino will interact in the way described, and give its symbol.

(Reference:
The AMANDA 677 photon multiplier tubes embedded within the polar ice sheet to depths of over 2km. These tubes use the photoelectric effect to detect light. The metallic light-receiving surface within each tube is sensitive to light of wavelengths shorter than 605 x 10^2nm. The corresponding photon energy represents the minimum energy to eject a photoelectron. What is the minimum photon energy in electron volts? State the kinetic energy of the photoelectron.)
