Electromagnetic Waves

Electromagnetic Waves
Transverse waves with some electrical properties and some magnetic properties.
An electromagnetic wave consists of changing __________ and ___________ fields.
electric, magnetic
Electric field
a region in which charged particles can be pushes or pulled.
Electromagnetic Spectrum
the name for the range of electromagnetic waves with the longest wavelengths and lowest frequencies.
the electromagnetic waves with the longest wavelengths and lowest frequencies
Radio waves with the shortest wavelengths and the highest frequencies
measuring instrument in which the echo of a pulse of microwave radiation is used to detect and locate distant objects- RAdio Detection And Ranging
Magnetic Resonance Imaging- MRI
a noninvasive imaging tech that produces highly detailed images of the brain using electromagnetic signals generated by the brain in response to magnetic fields.
Infrared Rays
Electromagnetic waves with wavelengths shorter than radio waves, but longer than visible light
Visible Light
A wave with shorter wavelengths and higher frequencies than radio waves- ex: rainbows
UV or Ultraviolet Rays
treats jaundice
shorter wavelenghts and higher frequencies than visible light
too much exposure = disease
higher frequency than uv rays but lower than gamma rays; used in medicine, industry, and to take picture of the inside of solid objects
Gamma Rays
Electromagnetic waves with the shortest wavelengths and highest frequencies
As wavelength ________ frequency _____________
decreases, increases
Magnetic Field
the lines of force surrounding a permanent magnet or a moving charged particle
