| Question | Answer |
|---|---|
| the diagram illustrating two waves in phase is: | it's the same |
| which of the following usually occurs inside a material instead of at the surface? | absorption |
| a violin string vibrates at a fundamental frequency of 200 Hz. the frequency of the third harmonic for this string is | 600 Hertz |
| a longitudinal wave travels | in the same direction as the oscillations |
| how many anti-nodes does this standing wave have <><><> | 3 |
| an ocean has a frequency of 2 Hz and a speed of 20 m/sec. What is the wavelength of this wave? | 10 meters |
| if you double the frequency of a pendulum, what happens to the period of one cycle? | the period is 1/2 its original time |
| a mass oscillates on the end of a spring with a period of 4 seconds. what is the frequency of the oscillator? | .25 Hz |
| natural frequency is: | the frequency at which a system oscillates when it is disturbed |
| a transverse wave: | oscillated perpendicular to the direction of wave travel |
| although a door is only slightly open, sound will pass from one room to another due mainly to: | reflection |
| sound waves are always: | longitudinal waves |
| which factor listed below has the greatest effect on the period of a pendulum? | length of the string |
| destructive interference occurs because: | multiple waves combine to make a wave of smaller amplitude |
| the wavelength of a wave is defined as | the distance from crest to crest |
| when a guitar is plucked it vibrates at its fundamental. If a guitar string is 68 cm long, what is the speed of the wave on a string if the fundamental frequency of the guitar string is 262 hertz? | 356 m/sec |
| eyeglasses bend light waves by the process of | refraction |
| the amplitude of a pendulum is doubled. this means | the pendulum will swing twice as far away from the center. |
| when a wave reflects from a hard surface, it may do all of the following except- | change from transverse to longitudinal |
| if the length of a pendulum increases, the period of the pendulum | increases |
| a vibrating string has a natural frequency of 30 hertz the string will also be resonant at | 60 Hertz |
| a piano is the approximate wave length in centimeters of this sound wave if the speed of sound in air is 340meters per second? | 77 centimeters |
| time for one cycle to occur | period |
| a single unit of periodic motion | cycle |
| distance from one point on a wave to the same point on the next wave | wavelength |
| unit of measurement for frequency (one cycle per second) | Hertz |
| happens when two or more waves interact | interference |
| multiples of the fundamental | harmonics |
| a group chosen to include all those thing of interest to be studied | decibel |
| a system that shows harmonic motion | oscillator |
| the maximum response to an oscillating force occurring at a natural frequency | resonance |
| number of cycles that occur in one second | frequency |
