The potential difference between the target and the cathode of an X-ray tube is 50kV and the current in the tube is 20mA. Only 1% of the total energy supplied is emitted as X-radiation. What is the maximum frequency of the emitted radiation? At what rate must heat be removed from the target in order to keep it at a steady temperature.

When photons pass through matter, the intensity I of the beam (measured in watts per square meter) decreases exponentially according to I = I0e-μxwhere I is the intensity of the beam that just passed through a thickness x of material and I0 is the intensity of the incident beam. The constant μ is known as the linear absorption coefficient, and its value depends on the absorbing material and the wavelength of the photon beam. This wavelength (or energy) dependence allows us to filter out unwanted wavelengths from a broad-spectrum x-ray beam.(a) Two x-ray beams of wavelengths λ1 and λ2 and equal incident intensities pass through the same metal plate.
