| Now researchers have used a slab of a new kind of material to focus diverging electromagnetic waves into a narrow cone. |
| The sources of classical electromagnetic waves are accelerating electric charges. |
| All the light that we see is made from electromagnetic waves, and so are infra-red and ultraviolet light, microwaves, radio waves and X-rays. |
| When a nuclear device is detonated, it emits a broad spectrum of electromagnetic waves that radiate outward from the detonating bomb. |
| In my opinion, this project is particularly important at a time when the impact of electromagnetic waves is being called into question. |
| The nature of nerve impulses, however, differs entirely from electromagnetic waves and sound waves. |
