| Question | Answer |
| What is the definition of a wave? | A disturbance that CARRIES ENERGY |
| The top of a wave is called what? | CREST |
| The bottom of a wave is called what? | TROUGH |
| The distance from one point on a wave to the same point on the next wave… often measured from crest to crest | WAVELENGTH |
| The height of the wave from the EQUILIBRIUM line | AMPLITUDE |
| What is A? | WAVELENGTH |
| What is B? | AMPLITUDE |
| What is C? | TROUGH |
| What is D? | CREST |
| What is E? | EQUILIBRIUM line |
| A type of wave where the disturbance is PERPENDICULAR to the motion of the wave | TRANSVERSE |
| A type of wave where the disturbance is Parallel to the motion of the wave | LONGITUDINAL |
| What type of wave is shown? | LONGITUDINAL |
| Give an EXAMPLE of a wave that travels like the wave shown | SOUND |
| What type of wave is shown? | TRANSVERSE |
| Give an EXAMPLE of a wave that travels like the wave shown | WATER LIGHT X-RAYS GAMMA Rays MICROWAVES RADIO WAVES INFRARED ULTRAVIOLET |
| The UNIT for wavelength | METERS |
| The UNIT for frequency | HERTZ |
| The UNIT for wavespeed | METERS/SECOND (m/s) |
| Definition of FREQUENCY | How many waves pass a given spot per second. Measured in Hertz (waves/second). |
| Physical wave that requires a medium (matter) to move through. | MECHANICAL |
| Physical wave that DOES NOT require a medium (matter) to move through. | ELECTROMAGNETIC |
| A change in the direction of a wave at a boundary between two media so the wave returns to the medium from which it originated | REFLECTION |
| When two waves OVERLAP to form a wave of greater, lower or same amplitude, occurs when two waves are traveling along the same medium | INTERFERENCE |
| What type of INTERFERENCE is shown? | CONSTRUCTIVE INTERFERENCE |
| What type of INTERFERENCE is shown? | DESTRUCTIVE INTERFERENCE |
| Waves 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 |
| The 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 |
| The happens when the frequency of a nearby object matches the natural frequency of a vibrating system and results in increased amplitude. | RESONANCE |
| Give 3 examples of RESONANCE we talked about in class | 1. Pushing someone on a swing 2. Tacoma Narrows Bridge 3. Breaking a glass with your voice |
| What kind of wave is sound? Pick 2. | Longitudinal Mechanical (requires medium) |
| What determines the PITCH of sound? | FREQUENCY |
| What determines the VOLUME of sound? | AMPLITUDE |
| What 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. |
| If 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. |
| How 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. |
| What type of wave is LIGHT? Pick 2 | Transverse Electromagnetic |
| List radiation type on the electromagnetic spectrum from LOWEST to HIGHEST Energy | Radio Waves Microwaves Infrared Visible Light Ultraviolet X-Rays Gamma Rays |
| List the colors of visible light from LOWEST to HIGHEST energy | Red Orange Yellow Green Blue Indigo Violet |
| Which 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) |
| Which 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) |
| What speed do all electromagnetic waves travel at? | Speed of LIGHT! (3 X 10^8 m/s) |
