Confusing true or false science questions?

1. Sound is caused by an echo





2. Infrasound is used to clean glassware





3. The bowl of a kettledrum that amplifies sound is called an echochamber





4. Loudness is determined by the pitch of a sound





5. As you move away from a warning siren, the pitch decreases





6. Multiples of the fundamental frequency are called beats.





7. Music is sound without a set pattern





8. Ultrasound is used to study body organsConfusing true or false science questions?
There are a couple that I am not sure about.


1. False echo is reflected sound


2. True I think ( not sure, but makes sense) It is used to clean diamond rings, so i would guess glass also.)


3. False ( again not sure)


4. False amplitude is what determines loudness


5. True doppler effect


6. True


7 False Noise has no pattern


8. True had one just the other dayConfusing true or false science questions?
1. I think this is false, When a noise is made the sound is carried by the vibration of the object causing the air molecules around it to vibrate in a certain way, this in turn causes your ear drum to vibrate at a certain frequency which is how you hear the sound. An echo is simply the sound bouncing off an object and coming back, in doing this it is not reflected cleanly (think of a reflection on a pond or something) so some of the quality is lost.





2: dont know sorry.





3: sounds plausible enough, should be easy to google this one.





4: Loudness is to do with the initial impact so therefore the speed of the vibration of the sound waves. The pitch of a sound is in reference to the highness or lowness of a sound.





5: The pitch will decrease, this is known as the doppler effect, this is similar to the echo, as you move away from a sound source the quality of sound that you hear decreases as the waves spread out. The higher pitch sound waves tend to be lost more easily than the low (think how well bass travels compared to high notes)





6: The frequency of a note is how often (normally) per second the note is repeated. So this could be correct, depending on how your trying to decribe beats...





7: I'd say its the opposite. Music is sound WITH a set pattern. Sound without a set pattern is just noise.





8: Ultrasound is used to study pregnant women's unborn babies. Kidneys and other parts.
