The pitch of a sound wave corresponds to what for a general wave? * 10 points wavelength O frequency O amplitude period The volume of a sound wave corresponds to to what for a general * 10 points wave? O wavelength frequency O amplitude period What type of wave is a sound wave? Select all that apply. * 10 points V mechanical wave electromagnetic wave transverse wave V longitudinal wave A sound wave in a tube or a string is a special case of a wave called * 10 points waves. Your answerThese waves in tubes or springs are created by __ and in the tube * 10 points or string. Select all that apply. (echolaction - locate objects with sound rather than sight.) reflection interference the doppler effect echolocation ultrasound1. Cut the straw so the bendy part is gone and you're left with a long straight straw. 2. Cut a V into one end of the straw, so that you get a point at one end (as shown in the picture). 3. Chew on the pointed end a little bit so that the straw is a little bit more flexible and the two flaps are closer together. 4. Blow air into the pointed end of the straw until a clear sound is produced. It might be kind of quiet, so you'll have to listen carefully. 5. Once you have a clear sound, slowly start snipping small pieces off the end of the straw to shorten the length of the tube. Listen to the sound it produces, then clean up ALL the pieces of the mess you've just made :) Straw oboe Are you done cleaning? 5 points Yes? Move on to the questions in the next section! O No? Clean up, then move on to the next section :)Explain your observations as you began cutting pieces off the end of * 10 points the straw. Your answer What is the relationship between the length of the straw and the pitch * 5 points produced? The shorter the length of the tube, the _ the pitch. O higher lower What is the relationship between the length of the straw and the * 10 points frequency of the sound produced? The longer the straw, the _ the frequency. higher lower Why did chewing on the pointed end of the straw help to produce a * 10 points clearer sound? Your answer For tube instruments, like clarinets or flutes, how can the pitch of the * 10 points sound be changed without actually cutting the instrument? Your
