1. You made two determinations of the wavelength of the brightgreen mercury line, one based on the first order interference andthe other based on the second order interference. Which one do youthink is more precise? Explain why.
2. Why is the wavelength of the spectral lines that seem samecolor have slightly different wavelength when emitted by differentelement?
3. List some diffraction phenomena in your daily lifeexperience.
4. What does the spectrum from sunlight look like in thespectrometer? Give your thoughts comparing the spectrum with thewhite light from mercury?
