Radiation of a certain wavelength causes electrons with a
maximum kinetic energy of 0.95 eV to be ejected from a metal whose
work function is 2.55 eV. What will be the maximum kinetic energy
(in eV) with which this same radiation ejects electrons from
another metal whose work function is 1.81 eV?
In the Compton effect, an X-ray photon of wavelength 0.16 nm is

An x-ray photon is scattered from a free electron (mass m) at rest. The wavelength of the scattered photon is λ′, and the final speed of the struck electron is v. Part A Part complete What was the initial wavelength λ of the photon? Express your answer in terms of λ′, v, m, and the appropriate constants. For the wavelength of the scattered photon λ′ use the notation λf. (Hint: Use the relativistic expression for the electron kinetic energy.) Express...

5) What is the wavelength of light an electron that has an energy of 10,000 eV. What is the wavelength if it has 40,000 eV of kinetic energy. By what fraction has the wavelength changed? (me for an electron is 0.511 x10° eV] Why are electron microscopes sharper than light microscopes. Compare the wavelength of green light (520 nm) to that of the 40,000 eV electrons. How many times is the electron wavelength smaller? What would the wavelength of a...
