Waves
This is a disturbance or movement that transfers ENERGY without permanent displacement
What are waves?
Waves which can move in matter or a vacuum such as light, radio, or microwaves.
What are electromagnetic waves?
A wave that transfers energy from a vibrating object through matter.
In the 17th century, Sir Isaac Newton used a prism to show that this type of light was a combination of many different colors of light.
What is sunlight or white light?
Distance from crest to crest or from trough to trough on a wave.
What is wavelength?
The form of waves which require a medium (matter) to move through such as water waves, sound waves, or slinky waves.
What are mechanical waves?
The type of electromagnetic radiation between infrared and ultraviolet light. The only light we see.
What is visible light?
Areas of longitudinal waves which are tightly pressed together by large amounts of energy.
What is compression?
This interaction with matter is occurring with the colors we see
What is reflection?
Shortest wavelength of light. This type of electromagnetic radiation can be harmful to living cells and tissue.
What is ultraviolet radiation?
The height of a rest or depth of a trough measured from rest position
What is amplitude?
An interaction with matter where electromagnetic waves bounce back intact.
What is reflection?
Areas of longitudinal waves that are spread apart due to relatively low energy.
What are rarefactions?
List the colors of a rainbow from shortest wavelength to longest wavelength.
What is
Violet, Indigo, Blue, Green, Yellow, Orange, Red
What are transverse waves?
The type of wave where matter moves back and forth in the same direction that the wave travels
What are longitudinal waves?
Communication technology encodes a pattern on this form of electromagnetic radiation which is transmitted to another device and decoded. The longest wavelength and lowest energy.
What are radiowaves?
Between sound waves and light waves, this one travels faster.
What is light waves?
The colors which are being reflected when we see something as black (is/are)
No color is reflected
When our eyes observe an object as being the color white, these colors are being reflected.
What are all colors?
The unit to measure wave frequency in cycle per second
What is Hertz?
An interaction with matter where electromagnetic waves are spread around.
What is diffraction?
As sound travels away from a source, the energy it caries does what?
What is decrease?
What is white?
The amount of time it takes for the sun's electromagnetic waves to reach the Earth.
What is 8 minutes?
