Waves Flashcards
A disturbance that transfers energy from one place to another without requiring matter to move the entire disturbance
Wave
A substance through which a wave moves
Medium
A wave such as a sound or seismic wave that transfer kinetic energy through matter
Mechanical wave
A wave in which the disturbance moves at right angles to the direction of the waves
Transverse wave
A type of wave in which the disturbance moves in the same direction that the wave travels
Longitudinal wave
The highest point or peak of the wave
Crest
The lowest point or valley of the wave
Trough
The maximum distance that a disturbance causes a medium to move from its rest position
Amplitude
The distance from one crest to the next wave crest
Wavelength
The number that pass a fixed point in a given period of time
Frequency
The bouncing back of a wave after it hits a barrier
Reflection
The bending of light as it crosses a boundary between two mediums at an angle other than 90 degrees
Refraction
The spreading out of waves as they pass through an opening or around the edges of an obstacle
Difraction
The meeting and combing of waves :the adding or subtracting of wave amplitudes that occur as waves overlap
Interference
A type of wave such as a light wave or radio wave that does not require a medium to travel through a disturbance that transfers energy through a field
Electromagnetic wave
Energy that travels across distances in the form of electromagnetic waves
Radiation
The range of all electromagnetic frequencies
Electromagnetic spectrum
The part of the electromagnetic spectrum that consists of waves of the lowest frequencies
Radio waves
Part of the electromagnetic spectrum that consist of waves with a higher frequencies than radio waves but lower frequencies than infrared waves
Microwaves
Part of the electromagnetic spectrum that consists of waves with a frequencies between those microwaves and visible light
Infrared light
The part of the electromagnetic spectrum that consists of wave of frequencies higher than those of visable light and lower than x rays
Ultraviolet light
The part of the electromagnetic spectrum that consists of waves with high frequencies and high energies;electromagnetic spectrum wave with frequencies ranging from 10 to the 16th power to 10 to the 21 power hertez
X-rays
Part of the electromagnetic spectrum that consists of waves with highest frequencies
Gamma rays
The passage of waves through a medium
Transmission
The disappearance of a wave into a medium ,the energy transferred by a wave is converted to a into another form of energy
Absorption
The spreading out of light waves in all direction as particles reflect and absorb the light
Scattering.
A way of filtering light so that all the waves vibrate in the same direction
Polarization
An optical tool that uses refraction of light to separate the different wavelengths that makeup white light
Prism
Three colors cyan,yellow and magenta that can be mixed to produce any possible colors
Primary pigments
Three colors of light red,yellow and blue that can be mixed to produce all possible colors
Primary colors
