This activity, from the Institution of Engineering and Technology (IET), looks at the properties and applications of waves in general, and the electromagnetic spectrum in particular. Students are asked to work out the type of electromagnetic radiation used in different imaging techniques.

The use of different types of signals is hugely important in all areas of healthcare. Signal processing engineers are involved in everything from extracting information from the body’s own electrical and chemical signals to using wireless signals to allow search-and-rescue robot swarms to communicate with each other.

The activity is supported by other resources in the Brainwaves collection which look at signals and imaging in healthcare, and the videos Mind mapping and Mind Control.

Curriculum links include the electromagnetic spectrum, medical physics, brain scans and the applications and implications of science.
