SOUND By Deborah Kim Kishan Patel
SOUND • Sound are produces by vibrations • Pitch • Infrasonic • Ultrasonic
Speed of Sound • Dry air at o° - 330 MPS or about 1200 KPH • One millionth of speed of light • Increase temp. increase sound
Sound in Air • Example slinky • Door
Depend on elasticity not on density • On steel 15 times faster than air • In water 4 times than air • Lake example
