Welcome to your Sound Waves(Senior Class Physics Study by Topics) NAME EMAIL PHONE NUMBER 1. How loud are noises in space?It's space, everyone knows there are no sounds in space.Never been there, I wouldn't know.Really loud, nothing out there to stop the sound wavesVery quiet with a few noises, almost like walking in the forest.2. 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?None of theseMultiple refractionsMultiple reflectionsWave motion3. If a sound wave travels 5 meters in 0.01567 seconds, what is the speed of the sound wave?4.984 m/s319 m/s5.01567 m/s0.07835 m/s4. The amount of force placed on an object that affects how tight or lose it is is called __________________.EnergySpeedTension5. 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?15000 m6000 m3500 m3000 m6. The bats can fly in the darkness of night without colliding with the other objects by emitting special sounds while flying. Which characteristic sound is used by the bats to navigate?InfrasoundAudible soundNone of theseUltrasound7. What is Intensity of Sound?BothIt is inversely proportional to the square of the distance of point from the source.It is directly proportional to the square of amplitude of vibration, square of frequency and density of the medium.None of the above8. All waves except __________ waves must travel through a medium. SoundCompressionalLightWater9. In this animation what kind of interference is shown? ConstructiveReflectionRefractionDestructive10. The material that a wave travels through is called the ReflectionMediumRefractionSpeed11. Which of the following can produce longitudinal as well as transverse waves under different conditions?None of theseTuning forkBatsSlinky12. Name the characteristic of the sound which distinguishes a sharp sound from a grave or dull sound?EchoResonanceIntensityPitch13. 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 ..............Shock wavesRefracted wavesBow wavesDoppler's waves14. Which of the following is not a type of electromagnetic wave? Gamma raysRadio wavesSoundRed light15. If the frequency of the wave is lowered, what happens to the speed of the sound wave?Sound wave slows downSound wave speeds upAll of the aboveSound wave speed does not change16. What type of waves are Sound Waves?Latitudinal mechanical wavesLatitudinal wavesLongitudinal wavesLongitudinal waves17. We can distinguish between a man's voice and a woman's voice of the same loudness even without seeing them. This is due to a characteristic of sound which measures the shrillness of sounds. Can you choose the correct unit of the quantity on which this characteristic of sound depends?Meter/secondHertzUnitlessMeter18. Which of the following statement is or are correct about longitudinal mechanical waves?The longitudinal mechanical waves having frequencies less than 20 Hz are called infrasonic.The longitudinal mechanical waves having frequencies greater than 20,000 Hz are called ultrasonic wavesThe longitudinal mechanical waves which lie in the frequency range 20 Hz to 20000 Hz are called audible or sound waves.All of the above are correct19. Sound waves are what type of wave?A surface waveA transvers waveA longitudinal waveA tidal wave20. The Hertz (Hz) is the unit of measure for which wave property? FrequencyWavelengthSpeedAmplitude21. In this animation, what type of wave is shown?LongitudinalRefractedTransverseLight22. What is the speed of sound in air?330 m/s336 m/s334 m/s332 m/s23. Sound travels best through ___________________.AirSolidWater24. The type of wave shown is a __________ wave.LongitudinalSoundTransverseLight25. What will be the effect of temperature on speed of sound?The speed of sound decreases with the decrease of temperature of the medium.The speed of sound decreases with the increases of temperature of the medium.The speed of sound increases with the decrease of temperature of the mediumThe speed of sound increases with the increase of temperature of the medium.26 out of 25Time is Up!
