I've been deep into this topic for a couple of days and it is becoming just more and more confusing. I am yet a beginner so i would like explanations to be detailed and easy. Moving directly, my doubt is.. We treat stars as black bodies which emit radiation... From where did the stars originally get their energy or atleast energy of all wavelength from.. Fusion?? .. Secondly, how do we detect the elctromagentic radiation.. Is it by naked eyes on a specific telescope or something.. Importantly, it is given in my book the spectral lines of different stars... O B A .etc... How u would clasify that for example all O class stars would have the same composition.. And i can see a trend in the lines from O to M class... I just need a detailed explanation of these spectral line.. And how would an object which orignally showed contionous spectrum would actually show and absorbtion spectrum?? I really really need the help.. It is urgent... Pass by any sentence.. It is worth reading every word in this topic... Please reply... Thanks in advance to whoever dominates in giving me the answer
