Stellar Fingerprints: the Spectra of Stars

Seven practice problems are presented to physics pros in this assignment. Given the wavelengths, they perform computations for emission spectra. This brief worksheet makes an appropriate pop quiz.

Get ready to spark interest in electromagnetic radiation! This resource shares nine indelible inquiries that you can choose from to ignite understanding of spectra and the relationship between light and heat. The assessments that follow...

In this atomic spectra worksheet, students answer eighteen questions about wavelengths of light, the emission spectrum, energy of photons, the frequency of electromagnetic radiation and electrons in the excited state.

These attractive slides explain the basics of the electromagnetic spectrum and then display the emission spectra for a number of elements. argon, helium, hydrogen, xenon, neon and krypton are shown here and two graphs showing log scale...

Star light, start bright! What do the brightness and color of stars tell us about the stars we see at night? Learners explore the life of stars with an information-packed video. Topics include the relationship between mass and...

Hydrogen is odorless, colorless, and tasteless, but can we hear it? By taking the wavelengths of the atomic spectrum of radiation from hydrogen, the creator of the video shifts the waves into sound waves. Then, he shifts these waves into...

Not quite a star, not quite a planet ... what are brown dwarfs? Young astronomers learn the peculiarities of these heavenly bodies through a short video. The narrator explains the characteristics of brown dwarfs and the different types....

Students investigate the wavelengths of spectra lines for common atoms. In this atomic emission spectra lesson plan, students use a transformer and diffraction grating to observe the emission spectra of various atoms. They find the...

Using spectroscopes, high school astronomy, physics, or chemistry learners observe emission spectra from several different sources. This stellar NASA-produced lesson plan provides terrific teacher's notes and a student handout. Make sure...

This link takes you to a comprehensive unit that delves into emission spectra and supernovas. There are four parts: How and where elements are created, electromagnetic radiation, spectroscopy, and the newest technology for studying our...
