Calculate the energy in joules and eV of a 3.38 Angstrom wavelength
X-rays usually have wavelengths of one to ten angstroms. Calculate the energy in joules of photons with a 2-angstrom wavelength. Calculate the energy in kilojoules per mole of such two angstrom wavelength photons. Compare it with the bond energy of a carbon-carbon single bond (347 kJ/mol). Would you expect x rays to be able to participate in bond breaking chemical reactions? Why?
An X-ray photon has an energy of 35,000 eV. (1 eV = 1.6 x 10-19 Joules) (a) What is the energy of the photon in Joules? (b) What is the frequency of the X-ray? (c) What is the wavelength of the X-ray?
How do you calculate the stopping voltage and Ek (Joules) and Ek (eV) from the wavelength and frequency? Please give an example
