Spectrometer: i-d curve

Assignment

  1. Find the angle of minimum deviation of the prism.
  2. Plot the i–d (angle of incidence vs. angle of deviation) graph of the prism.
  3. Find the minimum deviation for Red, Yellow, Green, and Blue light. How does the minimum deviation of different colours change with wavelength?
  4. Let the angle of the prism be 50° and the refractive index of the prism be 1.33. Find the angle of minimum deviation.
  5. Find the dispersive power of a glass prism using the spectrometer apparatus.
