When light illuminates a diffraction grating with 7000 lines per centimeter, its second order maximum is at 62.4. What is the wavelength of the light?
 
  A) 363 nm B) 752 nm C) 633 nm D) 336 nm

Question 2

Atoms in crystals are typically separated by distances of 0.10 nm.
 
  What kinetic energy must a nonrelativistic electron have, in electron-volts, in order to have a wavelength of 0.10 nm? (melectron = 9.11  10-31 kg, 1 eV = 1.60  10-19 J, h = 6.626  10-34 J  s)
