1) say for example it asks you to define or state a law. like Wien's displacement law.
Can i just write the law like

or do i have to write "the black body radiation curve for different temperatures peaks at a wavelength inversely proportional to the temperature " - just got that from wikipedia.

A definition should definitely be written as a proper sentence. Most mark schemes will specify particular words that your definition must contain in order to get the mark.

That doesn't really answer my specific example. Thank you though.

You need to write it in words unfortunately. Not the wiki definition but the textbook one. What exam board btw? AQA?

Ah, sorry, I don't take physics so there's not really much I can say about the specific example, other than that the second definition you gave (the one from Wikipedia) is more like what examiners usually look for. It depends on the exam board, though.

Just say maximum radiant energy flux is inversely proportional to temperature, then write the equation for guaranteed marks

and I assume radiant energy flux = wavelength? :afraid:
okay thank you, i'll put that

yes or peak wavelength, ive seen some questions in edexcel refer to them interchangeably
