Electromagnetic Waves
a transverse wave composed of an oscillating electric field and a magnetic field that oscillates perpendicular to the electric field.
What is an electromagnetic wave?
The term referring to the COMPLETE range of wavelengths of electromagnetic waves.
What is the electromagnetic spectrum?
The electromagnetic wave that is given off by the sun.
What is ultraviolet?
Those materials that light passes through clearly.
What are transparent materials?
This is the term for the interaction of waves with other waves.
What is interference?
These move at a stunning 300,000,000 meters per second.
What is an electromagnetic wave?
The electromagnetic wave that is roughly the size of a building.
What is a radio wave?
The type of light the only vibrates in one plane, giving off a "blinding" light. This happens when sun is reflected off of snow or water.
What is polarized light?
What are translucent materials?
The type of interference when crest of one wave meets the crest of another wave traveling in the opposite direction. This increases the amplitude.
What is constructive interference?
The theory of light that concludes a beam of light behaves as a stream of particles that all moved in the same direction.
What is (Sir Isaac Newton's) particle theory of light?
Te electromagnetic wave that is roughly the size of a baseball.
What is a microwave?
When light rays from the sun pass through molecules or particles that redirect the light waves. This is seen in sunsets.
What is scattering?
Materials that absorb or reflect all of the light that strikes it.
What are opaque materials?
The type of interference when the crest of one wave meets a trough of another wave. This results in an amplitude of zero.
What is destructive interference?
The theory of light that assumes that light is a wave and not particle.
What is (Christian Huygen's) wave theory of light?
The electromagnetic wave that is roughly the size of a pinpoint and used in TV remote controls.
What is infrared?
This is why the sky looks blue.
What is scattering?
The law that sates, "The angle of reflection equals the angle of incidence".
What is the law of reflection?
A packet of energy, released from an electron as it returns to a lower energy level.
What is a photon?
Albert Einstein's theory that explains how light can behave as both a wave and a particle.
What is the wave particle theory?
The electromagnetic wave that is used to fight cancer cells.
What is a gamma ray?
The name for Red, Green and Blue, the colors added together in different proportions to produce virtually any color.
What are the additive primary colors?
Another name (the technical name) for farsighted-ness.
What is hyperopia?
A person with this type of sight has an eye lens that can adjust for objects far away, but it cannot focus on objects that are close.
What is a person who is farsighted?
