EMS wheel
A handy visual resource that could be used as a quick reference or revision aid for KS4 waves. Cut out the two discs and join together with a split pin. Turn the top disc to reveal information about part of the electromagnetic spectrum.
The information includes the use, frequency, wavelength for each part of the spectrum.
Students could make and keep a copy in their books or print a few to keep as reference material in the classroom.
