Flashcards in Test On Vocabulary Deck (24):
The transfer of energy without transferring matter
A wave of which needs a matter or medium to travel through
(Sound, Ripple, Sports Wave)
An Electromagnetic Wave is a wave that does not need a matter to travel through
(Radio, Microwaves, Infrared, Visible Light, UV, X-rays, Gamma)
Parts of the spectrum
Radio wave, Microwave, Infrared, Visible Light, Ultraviolet, X-rays, and Gamma rays
Radio Waves, and Microwaves
Radio and Microwaves can both be used for communication, but Microwaves are better because they have a higher energy. Also, they can be used for cooking
Infrared and Visible Light
Infrared can be used for thermal energy. Visible Light can be used for seeing everything. The colors of the rainbow (ROY G. BIV) are all based off of the Visible Light.
Ultraviolet Rays and X-rays
Ultraviolet Rays can be used for killing bacteria. When someone gets extremely sick, this Ray is used. X-rays can be used for seeing bones. Also, it is used by construction workers to see cracks in structures.
Gamma Rays are mainly used for killing bad cells. When a person gets cancer, these Rays are used to kill the cells, but they can also kill good cells.
The highest point of a wave
The lowest point of a wave
The time for a complete cycle to pass a given point.
The distance from crest to crest or trough to trough (meters)
(Compressional-compression to compression)
The distance between the crest to the resting point of a wave
The number of waves that pass a given point in a set period of time
A wave in which the energy travels the same direction as the disturbance
The point in a longitudinal wave where the matter is pushed closer together
(Sound Wave, Sliky)
The point in a longitudinal wave where the matter is spaced farther apart
A wave in which the energy travels perpendicular to the disturbance (or right angles)
When waves strike a surface and bounce back in another direction
The bending of waves when they pass through materials
Waves spread out as a result of passing through a narrow aperture or around an edge of a material
Frequency times wavelength
(Meters per second)
Speed divided by wavelength
