A) Calculate the wavelength of x ray emitted when 35-keV electron collies with on molybdenum target.

B) What is the operating potential of an X-ray tube, if it produces photons with a maximum energy of 6.43x10^-15 J?

C) A proton moves along x axis at a speed of 6x10^5 m/s. The mass of the proton is 1.67x10^-27 kg. What is the de Broglie wavelength of this proton?

D) Calculate the wavelength of an electron accelerated by a potential difference of 1.00x10^3 from rest.

E) A single electron orbiting a hydrogen nucleus moves from energy level E4 to E2. Calculate the energy in joules of the photon emitted due to this energy change.

F) As an electron orbits the nucleus, it can be thought of as a standing wave. Calculate the frequency of the wave if the electron is in the 4th energy level of hydrogen atom.

G) Calculate the time required for an electron in the third orbit of the hydrogen atom to make one revolution of the nucleus
