6. Types of spectra { 7 marks)(a) The ﬁgure on the right shows the Sun. if the telescope zooms in on Position B,which kind of spectrum (emission,absorption, or continuous} is most easilyto be observed? (b) The solar atmosphere is very faint compared with the solar disk (Le. theorange circle in the figure} and it istherefore not easy to observe thespectrum emitted from Position 3. Suggest an astronomical event that is suitablefor the observation of this spectrum. (c) State two pieces of information that can be measured/found by using stellar spectrum.
