Question2
A fellow student expresses opinion that because the Suns spectrum has only weak absorption lines of hydrogen, this element cannot be a major constituent of the Sun. How would you enlighten this person? If a red star and a blue star both have the same radius and both are the same distance from the Earth, that one looks brighter in the night sky?
