Light from a laboratory sodium lamp has two strong yellow components at 589.6 nm and 590.0 nm. This light falls normally on a transmission grating that contains 8000 lines per centimeter.

a. Calculate the slits spacing in the diffraction grating.

b. Calculate the angular separation between the first-order maxima of these two wavelengths.

c. How far apart in the first-order spectrum will these two lines be on a screen 1.2 m from the grating?

Light from a fluorescent lamp is observed through a cloud of cool nitrogen gas. Again, two students are having a discussion about the kind of spectra that they would see. Student 1: We would see absorption line spectra and the missing lines would correspond to the light from the fluorescent lamp. Student 2: I disagree. We would see an emission line spectrum corresponding to nitrogen. This would happen because the nitrogen gas would absorb some energy from the fluorescent lamp...
