Electromagnetic Waves
What are Photons?
A packet of electromagnetic energy.
The electromagnetic spectrum includes the following?
radio waves, infrared waves, visible light, ultraviolet rays, X-rays, and gamma rays.
A false or distorted image.
Secondary Colors?
New color that results when any two of the primary colors combined.
What is Intensity?
The rate at which a waves energy flows thorugh a given unit of area.
What is Electromagnetic Spectrum?
the full range of electromagnetic radiation
What is a Polarized Light?
A type of light including light with waves that vibrate in only one plane.
What are the Complementary Colors?
Any two of light that combines to form white light.
What are Electromagnetic Waves?
Waves travel through a vacuum, or empty space, as well as through matter.
What is Amplitude Modulation?
a method of transmitting a radio signal in which the amplitude of the carrier wave varies while its frequency remains the same.
What is Translucent?
A description of material that scatters light that passes through it.
What is Pigment?
Material that selectively absorbs certain colors of light and reflects other colors.
What are Electric Fields?
A field in a region of space that exerts electric forces on charged particle, a field produced by electric charges or by changing magnetic fields.
What is Frequency Modulation?
a method of transmitting a radio signal in which frequency of the carrier wave varies while amplitude remains the same.
What is an Opaque?
A description of a material that either absorbs or reflects all of the light that strikes it so nothing can be seen through it.
What are Complementary Colors of Pigment?
Any two colors of pigments that combine to make black pigment.
What are Magnetic Fields?
A field in a region of space that exerts on a magnetic force, a field produced by magnets, by changing the electric fields or by moving charges.
What is Thermograms?
a color-coded picture using variations in infrared radiation to show variations in temperature.
What is Diffuse Reflection?
Reflection that occurs when parallel light waves strikes through, uneven surface and reflection many different directions.
Red, Green, and Blue
