1-sound waves are longitudinal waves. 2- Sound waves characterized by compression (A) & refraction (B). |
1-wave length:the distance between two successive points in the wave that are characterized by the same phase of oscillation. 2- Frequency: the number of waves that pass a fixed point in unit time. |
1-Sound waves spread faster in the stiff matter. 2-Sound waves travel more faster in solid then liquid then gas as the particles more compressed & stiff in solids than liquid & gas. |
|
1-Hertz is the measurement unit of frequency . 2-1 Hertz >>1 cycle per second above and below the atmospheric pressure line. |
1-pitch of sound :Adescription of how sound seems high or low to a person. 2- loudness:Adescription of your awareness of the energy of a sound. |

1- Stiffness affect the spread out of sound waves. 2- Sound Waves travel slower in gas, faster in liquid & fastest in solid as the particles are compressed & close to each other. |
1-Amplitude is the distance of the crest or troughs of a wave form from the neutral line. 2-Decibel is the smallest unit measurement of sound waves. |
