Seven 'Top-Trumps'-style cards for the seven conventional regions of the electromagnetic spectrum. Each card features information about typical wavelength, frequency and the speed in a vacuum. There are also uses in communications, healthcare and food industries, and also risks at high and low power.
Each card features a 'wavelength' graphic and a symbol to indicate whether the radiation is ionizing or non-ionizing. The individual cards are nominally A4-sized, but it is easy to print them in a set at smaller sizes using the print option in Adobe Acrobat Reader.
The cards were designed for and have been used with GCSE classes, but are also suitable for A-level physics students. Standard form is used on some of the cards to denote the typical frequency or wavelength. Units for speed are written m/s.
The cards can be used in many ways - a sequencing activity (increasing wavelength, increasing frequency) or as a talking point prompt about the speed of electromagnetic radiation in a vacuum, or the uses and risks.
The set of seven cards (plus a title card) are included as the original Publisher document, and as a PDF.
