|
| He proved that white light is composed of all of the
colors of the rainbow. |
|
Who was Newton? |
| This triangular piece of glass or plastic disperses
white light into a spectrum. |
|
What is a prism? |
| Fraunhofer mapped over 600 of these in the solar
spectrum. |
|
What are absorption lines? |
| He was able to match the series of bright
lines in the laboratory spectra to the dark lines found in the solar spectrum. |
|
Who was Kirchoff? |
| The spectrum produced by sunlight is one of these. |
|
What is an absorption spectrum? |
| These three phenomena are responsible for producing a
rainbow. |
|
What are refraction, dispersion and reflection? |
| He discovered absorption lines in the solar spectrum. |
|
Who was Fraunhofer? |
| These are created in a spectrum when the light from a
hot object or dense gas passes through a cloud of cooler gas. |
|
What are absorption lines? |
| He worked with Kirchoff to catalog
the bright emission spectra for all of the then known elements. |

Who was Bunsen? |
