Mini-Quiz: Spectrometer Used in Chemistry

1. What does a spectrometer do to light from a burning material?

   It causes the object to burn brighterSorry, not correct. Try another button. It separates the various elementsGood try, but not right. Select another answer. It spreads the light into its spectrumThat is correct. You know about spectrometers.

2. How can an individual element be identified with a spectrometer?

   By examining its unique set of spectral linesCorrect. You are brilliant! By seeing how the element reacts with other elementsOops! Wrong answer. Re-read the question and try again. By measuring the distance between spectral linesSorry, not correct. Try another button.

3. How is the chemical composition of a material determined from its spectrum?

   By separating the spectral lines and measuring their intensityThat is correct. You know about spectrometers. By varying the spectrum when heating the materialGood try, but not right. Select another answer. You cannot find the composition with a spectrometerOops! Wrong answer. Re-read the question and try again.
