Constant temperature but range of wavelengths?
Why is there a range of wavelengths at a constant temperature? Why isn't it just one continuous wavelength? I'm doing GCSE, so a basic explanation would be helpful.
What aspect? Waves?

black body radiation
Something to do with quantum mechanics. I forget what though.
The reason it is not a continouse wavelength is probably to do with energy being released in discrete packets of energy.

Basically, Black is actually an absence of colour, meaning it absorbs all wavelengths of light. So when it emits them back out it will emit all wavelengths even though it is a constant temperature. The actual explanation is at A-Level but you don’t really need to know that...

It is one of those things that only actually makes sense once you go to the core of what is going on, but that would require a level of understanding well above that of GCSE. In the meantime you have to try and remember explanations that don't make any sense and just confuse you.

Hope there's no black body radiation in the test tomorrow, :P
