Please explain the answer for this problem.
1) 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.
It shows how to find the minimum photon energy given the light wavelength.
