Study Guide Wave Vocabulary
Wave - a disturbance that transfers energy from one place to another without requiring matter to move the entire distance.
Medium – a substance through which a wave moves
Mechanical wave – a wave such as a sound or seismic wave that transfers kinetic energy through matter
Transverse wave – a wave in which the disturbance move at right angles to the direction of the wave
Longitudinal wave – a wave in which the disturbance moves in the same direction as the wave.
Crest – the highest point in a wave
Trough – the lowest point in a wave
Amplitude – the maximum distance that a disturbance causes a medium to move from its rest position
Wavelength – the distance from one wave crest to the next wave crest
Frequency – the number of waves that pass a fixed point in a given period of time
Reflection – the bouncing back of waves after it hits a barrier
Refraction –the bending of light as it crosses a barrier between two mediums at an angle other than 90 degrees
Diffraction – the spreading out of light waves as they pass through an opening or around the edges of an obstacle
Interference – the meeting and combining of waves : the adding or subtracting of wave amplitude that occur as waves overlap.
Electromagnetic wave – a type of wave such as a light wave that does not require a medium to travel through, a disturbance that transfers energy through a field
Radiation – energy that travels across distances in the form of electromagnetic waves
Electromagnetic spectrum – the range of all electromagnetic frequencies
Radio waves – the part of the electromagnetic spectrum with the lowest frequencies
Microwaves – part of the electromagnetic spectrum that consists of waves with a higher frequency than radio waves but lover frequencies than infrared light
Infrared light - part of the electromagnetic spectrum that consists of waves with a frequency between those of microwaves and visible light
Ultraviolet light - - part of the electromagnetic spectrum that consists of waves with a frequency higher than those of visible light and lower than x-rays
Xrays - part of the electromagnetic spectrum that consists of waves with high frequency and high energy: electromagnetic waves with frequencies ranging from 10 to the 16th power and 10 to the 21st power hertz.
Gamma rays – part of the electromagnetic spectrum with the highest frequencies.
Transmission – the passage of waves through a medium
Absorption – the disappearance of wave into a medium. The energy transferred by a wave is converted into another form of energy.
Scattering – the spreading out of light in all directions as particles reflect and absorb light.
Polarization – a way of filtering light so that the waves vibrate in the same direction
Prism – an optical tool that uses refraction of light to separate the different wavelengths that make up white light.
Primary colors- three colors of light that can be mixed to produce all possible colors.
Primary pigment – three colors of substances that can be mixed to produce all possible colors.
