Elctoromagnetic Waves Flashcards
Electromagnetic spectrum
The completes range of electromagnetic waves placed in orders of increasing frequency
Electromagnetic wave
A transverse wave that is made up of vibrating electric magnetic fields… involves the transfer of electric and magnetic energy
Radio waves
Electromagnetic waves with the longest wavelengths and the lowest frequencies
Microwaves
Have shorter wavelengths and higher frequencies the radio wave do
Radar
A system that uses reflected radio waves detect objects and measure their distance and speed
Infrared rays
electromagnetic with wavelength shorter than those microwaves. Carey’s more energy then microwaves , and are often called heat ways.
Thermogram
An image that shows regions of different temperatures in different colors
Visible light
Electromagnetic waves that you can see
Ultraviolet rays
Electromagnetic waves with wavelengths with shorter wavelengths and higher frequencies than those of visible light. Carry more energy than visible light and can damage or kill living cells
X-rays
Electromagnetic waves with shorter wavelengths and higher frequencies than ultraviolet rays. Carry more energy than ultraviolet rays can penetrate
Gamma rays
Electromagnetic waves with the shortest wavelengths and highest frequencies. Have the greatest amount of energy and are the most penetrating.
