Vocabulary Test Waves Transfer Enegy Flashcards
Medium
Any substance that a wave moves through
Wave
Disturbance that transfers from one place to another
Mechanical wave
Waves that transfer energy through matter
Transverse wave
The direction in which the wave travels is perpendicular or at right angles to the direction to disturbance
Longitudinal wave
The wave travels in the same direction as the disturbance
Crest
The highest point or peak of a wave
Trough
The lowest point or valley of the wave
Amplitude
The maximum distance that a disturbance causes a medium to move Crome its rest position
Wave length
The distance from one crest to another crest
Frequency
Measures how often a wave occurs
Reflection
The bouncing back of a wave after it strikes a barrier
Refraction
The bending of a wave as it enters a new medium at a angle other then
Diffraction
The spreading out of waves through an opening or around the edge of an obstacle
Interference
The meeting and combining of waves
Electromagnetic wave
A disturbance that transfers energy through a field
Radiation
Energy that moves in the form of EM waves
Electro magnetic spectrum
The range of all EM frequencies
Radio waves
EM waves that have the longest wave length, the lowest frequencies, and the highest energies
Microwaves
EM waves with shorter wavelengths, higher frequencies, and higher energy that other radio waves
Visible light
The part of the EM spectrum that the human eye can see
Infrared light
Part of the spectrum consist of EM frequencies between microwaves and visible light
Ultraviolet light
Part of the EM spectrum consist of frequencies abbé those of visible light and particularly below those of x-rays
x-rays
The part of the electro magnetic spectrum that consists of waves with high frequencies and high energies
Gamma rays
Part of the electro magnetic spectrum that consists of waves with the highest frequencies
