These lines are still called 'Fraunhofer lines' in his honour.

Atomic absorption lines are observed in the solar spectrum and referred to as Fraunhofer lines after their discoverer.

Replies: I assume you are referring to the Fraunhofer lines.

Kirchhoff and Bunsen also explained the origin of Fraunhofer lines.

What are Fraunhofer lines?

He took the first photograph of the spectrum of a star in which the dark lines called Fraunhofer lines show (1872).

In 1871, optical redshift was confirmed when the phenomenon was observed in Fraunhofer lines using solar rotation, about 0.1 Å in the red.

These lines are still called Fraunhofer lines in his honour - although they had previously been noted by Wollaston in 1802.

This instrument enabled him to thermally detect across a broad spectrum, noting all the chief Fraunhofer lines.

The Fraunhofer lines used are shown in the table to the right of the figure.
