Electromagnetic Wave Flashcards
electromagnetic spectrum
The complete range of electromagnetic wave placed in order of increasing frequency.
electromagnetic wave
Made up of vibrating electric and magnetic fields that move through space or some medium at the speed of light.(transverse wave)
radio waves
Electromagnetic waves this the longest wavelengths and lowest frequency.
microwaves
Electromagnetic waves that have shorter wavelengths and higher frequencies than ratio waves.
radar
A system that used reflected radio waves to detect objects and measure their distance and speed.
infrared rays
Electronic waves with shorter wavelengths and higher frequencies than microwaves.
thermogram
An image that show regions of different temperature in different colors.
visible light
Electromagnetic radiation that can be seen with the unaided eye.
ultraviolet rays
Electromagnetic waves with wavelength 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.
