What lines would be missing for hydrogen in an absorption spectrum? What wavelengths are missing for hydrogen in an emission spectrum?
State whether it is true that “the A spectrum is AM0 and the B spectrum is AM1.5”. Explain why B is weaker than A across the whole wavelength range. Show how you estimate the surface temperature of the Sun using the given spectrum.
A lightbulb manufacturer makes bulbs with different "color temperatures," meaning that the spectrum of light they emit is similar to a blackbody with that temperature. Assuming the emitting areas of the filaments in two bulbs with color temperatures of 2,000 K and 4,000 K are the same, which of the two is the brighter? About how much brighter is this bulb than its companion?
