A crystal has regularly spaced atoms that can act like a diffraction grating (which has many evenly spaced slits). Diffraction patterns form when the wavelength of a photon is similar in size to the spacing between atoms. Consider a crystal where the atomic spacing is 0.23 nm, and a photon of wavelength equal to this spacing. What part of the electromagnetic spectrum is such a photon? O infrared Ovisible light O ultraviolet gamma ray Ox-ray What is the momentum of this photon? Pph = kg-m/s Note that you will need to use exponential notation for your answer. Express it using "E": 1.23 x1024 is entered as 1.23E24. Particles such as electrons can act like waves just as photons do. In fact, they can be diffracted in just the same way by a crystal. What momentum would an electron have if its wavelength equals that of the photon (per the previous answer)? kg-m/s (Use exponential notation as above) What is the velocity that such an electron would have? For reference, the electron mass is 9.11 x10-31 kg. Ve Pe= m/s

The atoms in a crystal lie in planes separated by a few tenths of a nanometer. Can a crystal be used to produce a diffraction pattern with visible light as it does for x-rays? Explain your answer with reference to Bragg’s law.
Josef von Fraunhofer made the fi rst diffraction grating in 1821 and used it to measure the wavelengths of specifi c colors as well as the dark lines in the solar spectrum. His first diffraction grating consisted of 262 parallel wires. Assume that the wires were 0.20 mm apart and that Fraunhofer could resolve two spectral lines that were defl ected at angles 0.50 min of arc apart. Using this grating, what is the minimum separation (in wavelength) that can be resolved of two fi rstorder spectral lines near a wavelength of 400 nm?
