Problem 16. Find the maximum energy in eV of an x-ray photon produced by electrons accelerated through a potential difference of 50.0 kV in a CRT like the one show below. Metal target X rays High- voltage source Vacuum Electrons Heated filament Filament voltage X rays are produced when energetic electrons strike the copper anode of this cathode ray tube (CRT). Electrons (shown here as separate particles) interact individually with the material they strike, sometimes producing photons of EM radiation.
When photons with a wavelength of 310 nm strike a magnesium plate, the maximum velocity of the ejected electrons is 3.45 105 m/s. Calculate the binding energy of electrons to the magnesium surface in KJ/mol.
Characteristic x-rays: 30 keV electons emitted X-ray spectrum (shown below) is measured. are incident on a copper (atomic number- 29) target and the (a) Explain what are the how are they produce? peaks labeled Ka and Kp and What is the wavelength of characteristic Ks X-rays of Cu? (b) What is minimum wavelength (Jmin) of the emitted x-rays? (c) If the characteristic La X-rays are also the same as those of Ka X-rays? Explain your answer. observed, would their wavelength...
The X-ray experiment in the 1st year laboratory involves a high voltage (up to 28 kV) source of electrons which hit a target made of copper. This causes the electrons to decelerate, which results in the emission of "Bremstrahlung" X-rays, as well as characteristic peaks. The maximum X-ray energy is 28 keV. The door of the X-ray set is made of leaded glass. This attenuates the X-rays, according to the following equation: lo exp (-ut) Here l is the transmitted...

Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 42 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 49 cm . What is the wavelength of the sound? If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum?
