Welcome to your Sound Waves(Senior Class Physics Study by Topics) NAME EMAIL PHONE NUMBER 1. What is the speed of sound in air?330 m/s336 m/s332 m/s334 m/s2. The type of wave shown is a __________ wave.SoundLongitudinalLightTransverse3. The amount of force placed on an object that affects how tight or lose it is is called __________________.EnergyTensionSpeed4. What is Intensity of Sound?It is inversely proportional to the square of the distance of point from the source.BothIt is directly proportional to the square of amplitude of vibration, square of frequency and density of the medium.None of the above5. If the frequency of the wave is lowered, what happens to the speed of the sound wave?Sound wave slows downSound wave speeds upSound wave speed does not changeAll of the above6. Sound waves are what type of wave?A surface waveA longitudinal waveA tidal waveA transvers wave7. Another term for a sound reflection off of a wall or other object through which a sound wave cannot pass isReverbEchoVibrationAmplitude8. The Hertz (Hz) is the unit of measure for which wave property?WavelengthSpeedAmplitudeFrequency9. _________________ is the highness or lowness of a sound.VolumeTensionPitch10. If a sound wave travels 5 meters in 0.01567 seconds, what is the speed of the sound wave?0.07835 m/s5.01567 m/s319 m/s4.984 m/s11. The higher the amplitude, the __________________ the sound.LouderHigherLowerQuieter12. How loud are noises in space?It's space, everyone knows there are no sounds in space.Very quiet with a few noises, almost like walking in the forest.Never been there, I wouldn't know.Really loud, nothing out there to stop the sound waves13. When a motor boat in a sea travels faster than sound, then waves just like shock-waves are produced on the surface of water. These waves are called ..............Bow wavesShock wavesRefracted wavesDoppler's waves14. The material that a wave travels through is called theReflectionMediumRefractionSpeed15. The echo-receiver of a sonar attached to a ship, receives the echo from the bottom of sea 4 seconds after the ultrasonic waves were sent into the sea. If the speed of sound in water is 1500 m/s, then what is the depth of the sea?3500 m3000 m6000 m15000 m16. A movement back and forth that produces sound is called _____________VibrationAirSound17. The speed of the vibration is called ___________________.PitchRhythmFrequency18. All waves except __________ waves must travel through a medium.CompressionalSoundLightWater19. The speed at which a wave travels.Doppler effectWave SpeedWave heightWave length20. Which of the following is not a type of electromagnetic wave?Gamma raysSoundRadio wavesRed light21. In this animation, what type of wave is shown?LightLongitudinalRefractedTransverse22. Sound travels best through ___________________.AirWaterSolid23. Which of the following is/ are not applications of Ultrasonic Waves?(a) For measuring the depth of Sea.(b) In sterilizing of a liquid.(c) In Ultrasonography(d) In sterilizing a needle.Only (b)Both (a) and (b)Only (d)Both (c) and (d)24. You must have seen the doctor checking the sounds produced in the chest or heart beat of a patient using a medical instrument called Stethoscope. On what principle does this Stethoscope work?Wave motionMultiple reflectionsMultiple refractionsNone of these25. If the speed of a wave is 380 m/s and its frequency is 1900 Hz, then the wavelength of the wave will be:20 m200 m0.2 m2 m26 out of 25Time is Up!
