The moon blocks the radiation emitted by the photosphere,and the radiation emitted by the chromosphere reaches the earth.

Vedclass · Answer

(D) The solar spectrum consists of a continuous spectrum from the photosphere with dark absorption lines known as Fraunhofer lines. During a total solar eclipse,the moon completely covers the bright photosphere of the sun. As a result,the intense continuous light from the photosphere is blocked. However,the chromosphere,which is a thin layer of gas surrounding the photosphere,remains visible. The chromosphere emits a bright-line emission spectrum. Because the bright background of the photosphere is removed,the emission lines from the chromosphere become clearly visible,which are the reverse of the Fraunhofer absorption lines.
