A Spectral Mystery
It's no mystery that every gas has an emission spectrum. Scholars use a spectrograph to look at the emission spectra of nitrogen, oxygen, air, and other gases in gas discharge tubes. They use their results to determine the identity of a...

Typical Numeric Questions for Physics I - Photoelectric Effect
As the title implies, here is a collection of typical photoelectric effect problems that physics learners need to be able to solve. They determine the amount of energy of a photon, the photons produced per second, the frequency required...

Discovery 4-1 Atomic Emission Spectra
For this emission spectra worksheet, students use a spectroscope to observe three types of spectra. These include continuous spectrum, emission spectrum and absorption spectrum.

Stellar Fingerprints: the Spectra of Stars
Students explain how an element can be identified using emission spectra. They relate the emission spectrum of hydrogen to its absorption spectrum and identify hydrogen absorption lines in the spectrum of stars.
