Wave Basic Concepts

Cards in this deck (42)
- 1What is the definition of a wave?A disturbance that CARRIES ENERGY without transferring matter
- 2The top of a wave is called what?CREST
- 3The bottom of a wave is called what?TROUGH
- 4The distance from one point on a wave to the same point on the next wave… often measured from crest to crestWAVELENGTH
- 5The height of the wave from the EQUILIBRIUM lineAMPLITUDE
- 6What is A?WAVELENGTH

- 7What is B?AMPLITUDE

- 8What is C?TROUGH

- 9What is D?CREST

- 10What is E?EQUILIBRIUM line

- 11A type of wave where the disturbance is PERPENDICULAR to the motion of the waveTRANSVERSE
- 12A type of wave where the disturbance is Parallel to the motion of the waveLONGITUDINAL
- 13What type of wave is shown?LONGITUDINAL

- 14Give an EXAMPLE of a wave that travels like the wave shownSOUND

- 15What type of wave is shown?TRANSVERSE

- 16Give an EXAMPLE of a wave that travels like the wave shownWATER

ULTRAVIOLET
- 17The UNIT for wavelengthMETERS
- 18The UNIT for frequencyHERTZ
- 19The UNIT for wavespeedMETERS/SECOND (m/s)
- 20Definition of FREQUENCYHow many waves pass a given spot per second. Measured in Hertz (waves/second).
- 21Physical wave that requires a medium (matter) to move through.MECHANICAL
- 22Physical wave that DOES NOT require a medium (matter) to move through.ELECTROMAGNETIC
- 23A change in the direction of a wave at a boundary between two media so the wave returns to the medium from which it originatedREFLECTION
- 24When two waves OVERLAP to form a wave of greater, lower or same amplitude, occurs when two waves are traveling along the same mediumINTERFERENCE
- 25What type of INTERFERENCE is shown?CONSTRUCTIVE INTERFERENCE

- 26What type of INTERFERENCE is shown?DESTRUCTIVE INTERFERENCE

- 27Waves which appear to be vibrating vertically without traveling horizontally. Created from waves with identical frequency and amplitude interfering with one another while traveling in opposite directions.STANDING WAVES
- 28The frequency or frequencies at which an object tends to vibrate with when hit, struck, plucked, strummed or somehow disturbed is known as what?NATURAL FREQUENCY
- 29The happens when the frequency of a nearby object matches the natural frequency of a vibrating system and results in increased amplitude.RESONANCE
- 30Give 3 examples of RESONANCE we talked about in class1. Pushing someone on a swing
2. Tacoma Narrows Bridge
3. Breaking a glass with your voice - 31What kind of wave is sound? Pick 2.Longitudinal
Mechanical (requires medium) - 32What determines the PITCH of sound?FREQUENCY
- 33What determines the VOLUME of sound?AMPLITUDE
- 34What is the DOPPLER EFFECT?An increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other.

- 35If you scream in space, will anyone hear you? Explain :)NO, Sound is a MECHANICAL wave and as such requires a MEDIUM to travel through. Space is void of matter.
- 36How would you change the speed that sound travels?CHANGE THE MEDIUM it travels in. Changing the wavelength, frequency or amplitude does NOT change the speed of the wave.
- 37What type of wave is LIGHT? Pick 2Transverse
Electromagnetic - 38List radiation type on the electromagnetic spectrum from LOWEST to HIGHEST EnergyRadio Waves
Microwaves
Infrared
Visible Light
Ultraviolet
X-Rays
Gamma Rays - 39List the colors of visible light from LOWEST to HIGHEST energyRed
Orange
Yellow
Green
Blue
Indigo
Violet - 40Which type of radiation has HIGHER frequency .... radio waves or ultraviolet? How do you know?Ultraviolet (HIGHER frequency waves are on the RIGHT on the EMS)
- 41Which type of radiation has longer wave lengths ... radio waves or visible light? How do you know?Radio Waves (LONGER wavelengths are on the LEFT on the EMS)
- 42What speed do all electromagnetic waves travel at?Speed of LIGHT! (3 X 10^8 m/s)
