Find the energy of a photon with a frequency of 1 X 10¹6 Hz. 2. Things around you are emitting infrared radiation that includes the wavelength 9.9 X 10-6 m. What is the energy of these IR photons? 3. In what part of the EM spectrum would a photon of energy 9.5 X 1025 J be found? What is its energy in electronvolts? 4. Gamma rays (y-rays) are high-energy photons. In a certain nuclear reaction, a y-ray of energy 0.511 MeV (million electronvolts) is produced. Compute the frequency of such a photon. 5. Electrons striking the back of a conventional TV screen travel at a speed of about 8 X 107 m/s. What is their de Broglie wavelength? 6. In a typical electron microscope, the momentum of each electron is about 1.6 X 10-22 kg-m/s. What is the de Broglie wavelength of the electrons? 7. During a certain experiment,…
