Waves Vocabulary
Wavy
| Term | Definition |
|---|---|
| Waves | oscillations that carry energy |
| Oscillation | an up-and-down or back-and-forth motion |
| Vacuum | space that has no matter in it |
| Mechanical Waves | Waves that move through matter |
| Types of Mechanical Waves | e longitudinal waves, transverse waves, and surface waves. |
| Electromagnetic Waves | waves that move through vacuums |
| Types of Electromagnetic Waves | light waves, x-rays, and radio waves |
| Waves Properties | amplitude, wavelength, frequency, and Wave speed |
| Amplitude | one-half the distance between a wave's high point, or Crest, and low point, or trough |
| Crest | high point of a wave |
| Trough | low point of the wave |
| Resting Point | position the medium would take |
| Wavelength and Symbol | a point on one wave to the same point on the next wave fi there were no wave |
| Wavelength Units | m |
| 3 ways to measure wavelengths are: | crest to crest, trough to trough, and measure it from a certain distance to another |
| Frequency | number of waves that pass a fixed point a given unit of time |
| Units of Frequency | Hz(hertz) |
| Wave Speed | time it takes to move from one point to another |
| Wave Speed Units | (m/s) meters per second |
| Wave Speed Equation | frequency x wavelength |
| Medium (apply your reading for your definition) | substance that is applied to a wave |
| Reflection (and example) | when a waves off a surface |
| Law of Reflection | explains that waves get reflected in a particular |
| Reflected Ray | wave that will bounce off at 90 degrees |
| Incident Ray | wave that moves towards wall |
| Refraction (and example) | bending of waves as they travel different mediums. Ex: distorted waves of a pencil in a cup of water |
| Diffraction (and example) | bending of waves around a barrier or spreading of waves past small openings. Ex: ocean waves come through a jetty or pier |
| Interference | result of waves colliding with each other |
| Constructive Interference | when waves collide to become a bigger wave |
| Destructive Interference | waves that interfere with each other and cancel each other |
| Absorption | wave passing through a substance |
| Absorbed Colors | waves that are in the color of white light that separate out in into each distinct wavelength of light |
| Reflected Colors | waves that reflect off objects and enter our eyes |
| Electromagnetic Spectrum (know the order and be able to describe each) | {longest to shortest} radio waves (lowest-energy electromagentic waves), microwaves (between 0.3 and 0.003 m), infrared waves( longer than red light in the visible spectrum), visible light( light humans can see in the spectrum), UV Rays( smaller frequency |
| Visible Light Spectrum | colors of a rainbow, that are in the order of longest wavelength(red) to the shortest(violet)(Order: Red, Orange,Yellow, Green, Blue Indigo, Violet) |
| Longitudinal Wave | sound wave that oscillates in the same direction as it moves |
| Expansion | waves that expand that are more spread out |
| Compression | action or state of being squished down or made smaller or more pressed together. |
| Intensity (of sound) | the amount of energy the sound wave carries past a certain area |
| Units of Sound | db (decibel scale) |
| Pitch | perception of sound wave frequency |
| Analog Signal | signals that carry information but vary contiously in both amplitude and frequency |
| Digital Signal | signals that send information as wave pulses, and communicate through 1s and 0s, so the form that the information takes is much simplier |
