Electromagnetic Waves Flashcards
Electromagnetic spectrum
The complete range of electromagnetic waves placed in order of increasing frequency.
Electromagnetic waves
Waves that can transfer electric and magnetic energy through the vacuum of space.
Radio waves
Electromagnetic waves with the longest wavelengths and lowest frequencies.
Microwaves
Electromagnetic waves that have shorter wavelengths and higher frequencies than radio waves.
Radar
A system that uses reflected radio waves to detect objects and measure their distance and speed.
Infrared waves
Electromagnetic waves with shorter wavelengths and higher frequencies than microwaves.
Thermogram
An image that shows regions of different temperatures in different colors.
Visible light
Electromagnetic radiation that can be seen with the unaided eye.
Ultraviolet rays
Electromagnetic waves with wavelengths shorter than visible light but longer than X-rays.
X-Rays
Electromagnetic waves with wavelengths shorter than ultraviolet rays but longer than gamma rays.
Gamma rays
Electromagnetic waves with the shortest wavelengths and highest frequencies.
