In his explanation of the threshold frequency in the photoelectric effect, Einstein reasoned that the absorbed photon must have the minimum energy required to dislodge an electron from the metal surface. This energy is called the work function () of that metal. What is the longest wavelength of radiation (in nm) that could cause the photoelectric effect in each of the following metals? (a) Tungsten, = 7.16 10-19 J __nm (b) Tantalum, = 6.41 10-19 J __nm (c) Silver, =...

Explain the photoelectric effect in terms of energy. In your explanation, start with the energy of the incident EMR photons and finish with the energy of the stopping voltage. Be sure to include the following terms in your answer: threshold frequency, light intensity, photoelectron current, work function, photoelectron kinetic energy and stopping voltage.

how did the photoelectric effect prove that light had particle properties?

How does the Quantum Hall Effect? (Explanation, not its definition)

What basic assumptions did Einstein make in deriving his theory of Special Relativity? What experimental evidence, if any, was available at the time to support his conjectures? What are three counter-intuitive consequences of the theory? [15 pts - short essay] Explain time dilation. Use an example to show how it is derived. [10 pts - question] Most of the elementary particles we know about are unstable; they decay after a finite lifetime. (The muon is an example.) Only a few...
