Fusion and Fission leads to an increase in Binding energy per nucleon. Why is there an overall loss of mass if avg dinding energy per nucleon increases?

I'm not sure if this is totally accurate so please somebody correct me if I'm wrong. I think binding energy per nucleon is basically a way of expressing the energy needed to break apart the nucleons. Since this is effectively a measure of the 'lack' of energy and e=mc^2, higher binding energy per nucleon = lower mass.
Anyone got some good revision notes? I've been constantly pushing back revising for this exam cause it is my very last, and I need to start changing that, just so much to know.

I've been concentrating on my other exams too - got to really work on unit 5 this week! Personally, I don't find revision guides very useful so I revise by going over the past papers again and again, but some people like the edexcel revision guide, I think.
Nope no constants for astrophysics for some reason, unless you count the one in Wein's law.
Oh damn I was relying on that being in there (could've sworn it was haha)! I suppose in that case that's probably the best way of doing it then I sometimes remember it as 150 million kilometres but it's probably best to have a way of working it out too.
Thanks but how is it possible that a bunch of them overlap?
I guess it's something to do with the difference between consecutive wavelengths. Like if the difference between them is too small, then it can be quite difficult to differentiate which type of EM radiation is it.

But that would imply multiple answers are correct for a given wavelength? I've seen 2 of those questions so far asking to name the category, and only 1 is accepted

As I said, I just took a guess that this "might" be the reason behind the overlapping. Because I also feel a bit confused about it myself.(When I think in terms of the MCQs because if we considered overlapping, then we would have more than one possible answer and that's not possible!)
