1. The problem statement, all variables and given/known data I know there's the following sections: Abstract Introduction Method Used Results Data analysis Discussion Conclusion Awknowledgement References But when there are two areas of the experiment to be investigated, say measuring the wavelength of light for green and yellow using diffraction gratings, do you talk about them in these headings, or do you create these headings again for each part of the experiment? 2. Relevant equations 3. The attempt at a solution Thanks.
