Scoring top grades in IB Diploma, IGCSE or GCSE science is not just about intelligence — it is about how you revise. The students who consistently achieve the highest marks are not necessarily the ones who work the longest hours; they are the ones who use the right strategies. This guide brings together the most effective, evidence-based revision techniques to help you work smarter and perform at your best when it matters most.
Young's double-slit experiment is one of the most elegant demonstrations in physics. By passing light through two closely spaced slits, an interference pattern of bright and dark fringes is produced on a screen. Measuring the fringe spacing allows you to calculate the wavelength of the light used. This makes it an excellent IB Diploma Physics HL Internal Assessment investigation.
