Welcome to your Sound Waves(Senior Class Physics Study by Topics) NAME EMAIL PHONE NUMBER 1. Which of the following is not a type of electromagnetic wave? Sound Radio waves Red light Gamma rays 2. How loud are noises in space? Really loud, nothing out there to stop the sound waves Very quiet with a few noises, almost like walking in the forest. Never been there, I wouldn't know. It's space, everyone knows there are no sounds in space. 3. The lower the frequency, the _____________ the sound. Louder Lower Quieter Higher 4. Sound does not travel in space because No air, so there is no medium to travel through. Too dark Too many asteroids What? 5. In this animation what kind of interference is shown? Destructive Constructive Reflection Refraction 6. _________________ is theĀ highness or lowness of a sound. Tension Pitch Volume 7. The type of wave shown is a __________ wave. Longitudinal Transverse Sound Light 8. 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 waves Refracted waves Shock waves Doppler's waves 9. The Hertz (Hz) is the unit of measure for which wave property? Frequency Amplitude Speed Wavelength 10. Loudness measures the sound energy reaching the ear per second and depends on the amplitude of the sound wave. What is the unit used to measure the loudness of sound? Second Hertz Decibel Meter/second 11. If a sound wave travels 5 meters in 0.01567 seconds, what is the speed of the sound wave? 319 m/s 0.07835 m/s 5.01567 m/s 4.984 m/s 12. 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? None of these Ultrasound Audible sound Infrasound 13. Another term for a sound reflection off of a wall or other object through which a sound wave cannot pass is Reverb Vibration Echo Amplitude 14. The speed of the vibration is called ___________________. Rhythm Pitch Frequency 15. A movement back and forth that produces sound is called _____________ Sound Vibration Air 16. Sound waves are longitudinal waves which have _________________ and rarefactions. None of the above Crests Troughs Compressions 17. If the frequency of the wave is lowered, what happens to the speed of the sound wave? All of the above Sound wave speed does not change Sound wave slows down Sound wave speeds up 18. On increasing the temperature, the speed of sound in air: Does not change First increases then becomes constant Increases Decreases 19. Sound waves are what type of wave? A longitudinal wave A tidal wave A transvers wave A surface wave 20. The speed at which a wave travels. Wave length Doppler effect Wave height Wave Speed 21. The material that a wave travels through is called the Reflection Speed Medium Refraction 22. Before playing the orchestra in a musical concert, a sitarist tries to adjust the tension and pluck the string suitably. By doing so, he is adjusting (a) Amplitude of the sound (b) Frequency of the sitar string with the frequency of other musical instruments (c) Intensity of sound (d) Loudness of soundChoose the correct option: A and c Only b B and d 23. What type of waves are Sound Waves? Latitudinal waves Longitudinal waves Latitudinal mechanical waves Longitudinal waves 24. Which of the following can produce longitudinal as well as transverse waves under different conditions? Slinky Bats None of these Tuning fork 25. If the speed of a wave is 380 m/s and its frequency is 1900 Hz, then the wavelength of the wave will be: 200 m 2 m 0.2 m 20 m 1 out of 25 Time is Up! Time's up
