Questions and Answers

What relationship exists between particle size and the angle and intensity of scattered light in laser diffraction?

  • The intensity of scattered light is independent of particle size, but the angle varies
  • Large particles have more intense light scatters and smaller angles than small particles do (correct)
  • Small particles have more intense light scatters and smaller angles than large particles do
  • The angle of scattered light is independent of particle size, but the intensity varies

    • What is used to transform scattered light data into particle size in laser diffraction?

  • Rayleigh Scattering Theory
  • Raman Scattering Theory
  • Mie Scattering Theory (correct)
  • Thomson Scattering Theory

    • In laser diffraction, what type of particles have more intense light scatters and smaller angles?

  • Large particles (correct)
  • Both large and small particles have the same intensity of light scatters and angles
  • It depends on the material of the particles
  • Small particles
