Assignment

1. Calculate the number of lines per unit length of the given grating using the simulator.
2. Using green light as the standard, calculate the number of lines per unit length of the grating and hence obtain the wavelength of the red line of the spectrum.
3. Find the diffraction angle of the red line for the first-order spectrum of the mercury spectrum.
4. Compare the wavelength of red and violet lines of the mercury spectrum using a diffraction grating arrangement.
5. Obtain the wavelength of all prominent lines of the mercury spectrum using the diffraction grating arrangement.
