Core Describe the main features of the electromagnetic spectrum in order of wavelength and state that all e.m. waves travel with the same high speed in vacuum [|The electromagnetic spectrum] from nasa.gov
 * Properties of Electromagnetic Waves**

Describe typical properties and uses of radiations in all the different regions of the electromagnetic spectrum including: – radio and television communications (radio waves) – satellite television and telephones (microwaves) – electrical appliances, remote controllers for televisions and intruder alarms (infrared) – medicine and security (X-rays) [|The electromagnetic spectrum] from darvill.clara.net

Demonstrate an awareness of safety issues regarding the use of microwaves and X-rays [|Electromagnetic fields and cancer] from National Cancer Institute

State that the speed of electromagnetic waves in a vacuum is 3.0 × 108 m/s and is approximately the same in air. • State that all e.m. waves travel with the same high speed in a vacuum Speed of light: All EM waves travel at 300 million m/s in a vacuum media type="youtube" key="ZGF-jHUAPDQ" width="560" height="315" BBC James Clerk Maxwell media type="youtube" key="jnGTCaiZqOE" width="560" height="315" Limits of Light - The Secrets of Nature [|The Secrets of Nature] Published on 2 May 2014
