What are Fraunhofer lines? How are they useful in the identification of elements present in the Sun?

टीपा लिहा

उत्तर

When the spectrum obtained from the Sun is examined, it consists of a large number of dark lines (line absorption spectrum). These dark lines in the solar spectrum are known as Fraunhofer lines.
