Waves and EM spectrum knowledge mat for secondary schools
If every electromagnetic wave travels at the same speed, what makes a gamma ray dangerous and a radio wave harmless? Amplitude, wavelength, frequency and period, with transverse and longitudinal waves drawn side by side; the seven bands of the spectrum in order, with what each is used for; reflection, refraction, absorption and colour, under Röntgen's first X-ray of 1895; the three relationships with the recall/given chip; a worked wavelength from a frequency. Eight terms to define, a model answer on why gamma rays ionise, and the misconceptions that cost marks.
Everything else this site has for Science: Science teaching resources
One purchase covers the school that buys it. Print it, copy it, hand it round your department. Not for passing to other schools or uploading anywhere.
One landscape A4 page on one topic, led by the figures and photographs rather than the headings. It carries the wave quantities, transverse and longitudinal waves, the spectrum in order with its uses, what matter does to a wave under Röntgen's X-ray, and a worked wavelength — then the vocabulary, a worked exam-style answer and the misconceptions that cost marks.
Every photograph on the sheet is a real archival or scientific image, not an illustration and not AI-generated; every diagram is drawn in code for the sheet. Each image was checked against its own licence template rather than a label, and the running foot names every creator, states that the images have been cropped and adjusted for print, and links the licence — so the sheet can be photocopied for a class and stay compliant. Every claim is sourced to the DfE subject content, and nothing is reproduced from a past paper, a textbook or a specification.
Sold by subject: all four physics sheets for one price. A knowledge organiser stores a unit and is revised from afterwards; this is meant to be on the table while the work is happening.
- Written to The DfE GCSE subject content for physics (DFE-00353-2014). Every photograph is a sourced archival or scientific image, licensed for reuse and credited on the sheet; every diagram is drawn in code for the sheet
- Intended for physics teachers — on the desk during the lesson, not a student revision guide
