Properties Of Sound Chapter 16 Section 2

Properties Of Sound Why does sound travel fastest in solids? Particles are tightly packed.

Properties Of Sound What is pitch? If a wave has a high frequency what type of pitch does it have? How high or low a sound is. High

Properties Of Sound If a wave has a low frequency, what type of pitch does it have? Low

Properties Of Sound When does a wave become ultrasonic? What causes the Doppler Effect? When it goes over 20,000 Hertz. Motion of the listener or the source of sound.

Properties Of Sound What happens to the sound when there is a greater amplitude? More vibrations and louder sound. (When you hit a drum harder, it gets louder.) QuietLOUD

Properties Of Sound What unit is used to measure loudness? Decibels
