Handout Problems: 1. How does a noise sound when its frequency is increased? 1|When its amplitude is increased? 2. In what direction do sound waves traveling north cause the air particles over which they pass to vibrate? Is sound a transverse or a longitudinal wave\"? 3. Compare the speed in air of two sounds, one of frequency 2th} Hz and the other of 400 Hz. 4. 1|Why does sound travel Faster in water than in air? 1|Why does sound not travel at all in space? 5. A girl hears her echo return from a wall Illll s after shouting \"Boo!" IF the speed of sound is 33D mils, then how far is the girl From the wall? 6. The speed of sound increases by H.6- nu's for every degree Celsius rise in temperature: it = 33! We + (115 net'sCj-T A soldier hears the firing of a distant cannon t} seconds after seeing the ash.
