Electromagnetic Waves Flashcards
The full range of frequencies of the electromagnetic spectrum.
Electromagnetic spectrum
Transverse waves consisting of changing electric fields and changing magnetic fields.
Electromagnetic waves.
Using the amplitude of a wave to send a signal.
Amplitude modulation
Using the frequency of a wave to send a signal.
Frequency modulation
Color coded pictures that show variations in temperature.
thermogram
A material that lets light pass through.
Transparent
A material that scatters light.
Tansluscent
A material that either absorbs or reflects most light that hits it.
Opaque
A copy of an object formed by reflected r refracted waves of light.
Image
When parallel light waves strike a surface and reflect in the same pattern.
Regular Reflection
When parallel light waves hit an uneven surface and reflect in many directions.
Diffuse reflection
A false or distorted image.
mirage
Light with waves that only vibrate in one plane.
Polarized Light
The redirection of light as it passes through a medium.
Scattering
The process of separating white light into its colors.
Dispersion
