What if Anything is Wrong Task – Light Emission

This text discusses the emission and absorption spectra of hydrogen, clarifying a student's statement regarding the presence of bright lines in the emission spectrum and their absence in the absorption spectrum. It explains that the statement is incorrect as the missing lines are directly related to hydrogen. The text also explores the concept of light emission and absorption in hydrogen.

Presentation Transcript

  1. What if Anything is Wrong Task – Light Emission

  2. View the emission spectrum for Hydrogen

  3. Describe the emission spectrum of Hydrogen • It is a continuous spectrum like a light bulb • It consists of bright lines at distinct colors • It is like a rainbow

  4. View the absorption spectrum for Hydrogen

  5. A student makes the following comment.Student: “In the absorption spectrum for hydrogen, the hydrogen emits a continuous spectrum except at the wavelengths corresponding to the lines in the hydrogen emission spectrum.”

  6. Answer the following on your own

  7. What if anything is wrong with the student’s statement? • The statement is correct • The light is emitted by a source different than the hydrogen. The missing lines have nothing to do with hydrogen • The hydrogen emits at all frequencies just a smaller amount for the dark lines • Hydrogen absorbs light from another source, and reemits in all directions reducing the brightness

  8. Consult with your neighbors and answer again.
