1. Time Dilation- Atomic clocks

Homework Statement Two atomic clocks are synchronized. One is placed on a satellite which orbits around the earth at high speeds for a whole year. The other is placed in a lab and remains at rest with respect to the earth. You may assume both clocks can measure time accurately to many...
2. Colour of light producing photoelectrons?

Thank you both! very much appreciated :D
3. Colour of light producing photoelectrons?

Homework Statement a) calculate the energy, in joules, of a quantum of light with a wavelength of 590 nm. b)will this colour be able to produce photoelectrons from the surface of a metal with a work function of 3.0 eV? Explain your reasoning. Homework Equations f=c/λ E=fh ek=hf-W The Attempt...
