Electromagnetic waves Flashcards

Transverse waves that transfer energy from a source to an absorber. They travel at the same speed in a vacuum (300,000 km/s).

The continuous range of electromagnetic waves, ordered by wavelength or frequency.

Electromagnetic waves with the longest wavelength and lowest frequency. Used in communication like TV and radio.

Electromagnetic waves used in cooking and satellite communications. Can heat body tissues.

Electromagnetic waves used in heaters, remote controls, and thermal imaging. Can cause skin burns.

The part of the electromagnetic spectrum that humans can see. Used in vision and photography.

Electromagnetic waves used in tanning beds and sterilisation. Can cause skin cancer and eye damage.

Electromagnetic waves used in medical imaging. Can penetrate soft tissue but not bones.

Electromagnetic waves with the shortest wavelength and highest frequency. Used to kill cancer cells but can be harmful to living cells.

The bending of electromagnetic waves as they pass from one medium to another due to a change in speed.
