Electromagnetic Math

This series of activities from NASA take a mathematical approach to looking at electromagnetic radiation. They are intended as supplementary problems for students looking for additional challenges in mathematics and physical science from age 11 to 19 years. The problems were created to be authentic glimpses of...

Electromagnetic radiation

This activity, from the Institution of Engineering and Technology (IET), is one of a series of activities which explores body centric communications. Students study data and annotate a diagram to show what electromagnetic radiation can penetrate the atmosphere. The...

Electromagnetic Spectrum

Following a presentation on the electromagnetic spectrum, students are asked to produce a presentation which must include the following:

*How frequency is involved in categorising different waves.

Electromagnetic spectrum

• Identify types of electromagnetic radiation that can be naturally occurring.
• Describe a range of sources of harmful electromagnetic...

Electromagnetic spectrum poster

This poster shows how the electromagnetic spectrum has been divided into seven ‘types’ according to use, with a look at how the National Physical Laboratory (NPL) uses it in high precision measurement.

Electromagnetic waves

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...

Electromagnetic waves - wavelengths and frequencies

This video revises the order of electromagnetic spectrum (GCSE) and introduces the range of magnitudes of wavelengths and corresponding frequencies for each type of electromagnetic radiation.

Electromagnetic waves - why they are transverse

This video helps students to visualise the electric and magnetic field components of an electromagnetic wave.

The electric and magnetic oscillations (vibrations) are at 90⁰ to each other and also to the direction of energy propagation.
