SOUND

Learn about sound waves, vibration, and how sound travels through different mediums!

1. What produces sound? the vibration of objects the parts of a device like radio the ineteraction between objects the movement of molecules 2. What is vibration? the up and down movements objects the back and forth movement of objects the risng and falling of objects none of the above 3. Which of the following statements is NOT true? Striking an object creates vibration and produces sound. All vibrations are not visible to the eye. Some vibrations are visible and some are not. Vibrations produce waves such as sound. 4. What is a medium? something that is in a middle position the thing by which or through which something is done the object through which sound travels none of the above 5. Sound waves CANNOT travel through which of the following? solids liquids gases vacuum 6. What is vacuum? outerspace the absence of matter the absence of sound an electrical apparatus we use to collect dust and small particles from the floor 7. Which of the following statements is correct? Vibrations cause the particles of a medium to travel to the ears. Vibrations produce a disturbance that travels through the medium. The particles of the vibrationg object travel through the medium. none of the above 8. What happens to the surrounding particles of a medium when the prongs of a tuning fork are displaced away from their mean position? a low pressure region called rarefaction is created a high pressure region called rarefaction is created a low pressure region called compression is created a high pressure region called compression is created 9. What happens to the surrounding particles of a medium when the prongs of a tuning fork are displaced towards their mean position? a low pressure region called rarefaction is created a high pressure region called rarefaction is created a low pressure region called compression is created a high pressure region called compression is created 10. When the particles of a medium are compressed, they are _. close to each other creating a high density area close to each other creating a low density area far from each other creating a low density area far from each other creating a high density area 11. Sound waves travel in the form of _. rarefactions only compressions only rarefactions and compressions neither rarefactions nor compressions 12. Waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of propagation of the wave are _. transverse longitudinal mechanical electromagnetic 13. Sound waves are also called _. surface waves pressure waves density waves electromagnetic waves 14. Waves in which the motion of the particles is perpendicular or at right angle to the direction of wave travel are said to be _. longitudinal transverse mechanical electromagnetic 15. Sound waves are _ waves. longitudinal transverse surface electromagnetic
