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
The name for the colors red, green, and blue that make up other colors
Primary Colors
A color that comes from the mixing of two primary colors.
Secondary color
The name for two colors that combine to form white.
Complimentary colors
A material that absorbs some colors of light and reflect other colors.
Pigment.
Any two colors of pigment that combine to form black
complimentary colors of pigment
Objects that give off their own light.
Luminous
Light that is produced when an object gets hot enough to glow.
Incandescent
When a material absorbs light at one wavelength of light and emits light at a longer wavelength of light.
Fluorescence
A device that emits a beam of coherent light.
Laser
