Electromagnetic Waves Flashcards
radio waves, microwaves, infrared rays, visible light, ultraviolet rays,
X-Rays, and gamma rays
electromagnetic spectrum
a transverse wave made up of vibrating electric and magnetic fields that move through space or some medium at the speed of light
electromagnetic waves
electromagnetic waves with the longest wavelengths and the lowest frequencies
radio waves
waves with a shorter wavelength and higher frequency than microwaves
microwaves
a system that uses reflected microwaves to detect objects and measure their distance and speed
radar
electromagnetic waves with wavelengths shorter than those of microwaves; called heat rays
infrared rays
an image that shows regions of different temperatures in different colors
thermogram
electromagnetic waves you can see
visible light
electromagnetic waves with a wavelength just shorter than that of visible light; can kill or damage living cells
ultraviolet light
electromagnetic waves with a wavelength just shorter than ultraviolet light; can penetrate most matter
X-Rays
electromagnetic waves with the shortest wavelengths and highest frequencies. Have the greatest amount of energy and are the most penetrating.
gamma rays
