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
