Learn about the electromagnetic spectrum, the order of the waves, their uses and dangers with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

Electromagnetic waves travel at 300,000,000 metres per second (m/s) through a vacuum. Often a phrase is used to help remember the order of the groups of the electromagnetic spectrum such as Roman ...

All forms of electromagnetic radiation, whether they're called waves or rays, are generated by particles in motion. In a radio signal, for example, negatively charged electrons quickly move back ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could ...

Researchers demonstrated that specific electromagnetic wave frequencies can disrupt the SARS-CoV-2 Spike protein structure in virus-like particles, leading to reduced infectivity in cell models.
