State fraunhoffer''s lines, Physics

Assignment Help:

 The central part (photosphere) of the sun is very hot and  all possible wavelengths of the visible light. Though, the outer part (chromospheres) having of vapours of dissimilar components. When the light emitted from the photosphere passes by the chromospheres, certain wavelengths are real, as, in the spectrum of wave a large number of dark lines are seen known as Fraunhoffer lines.
