1. X-rays of wavelength 0.1400 nm are scattered from a very thin slice of carbon. What will be the wavelengths of X-rays scattered at 120°.
2. Determine the wavelength of light emitted when a hydrogen atom makes a transition from the n = 6 to the n = 3 energy level according to the Bohr model.
3. Calculate the longest and shortest wavelengths of light in the Lyman, Blamer and Paschen series of the Hydrogen atom.
