Is the distance between two successive compression Or rarefaction.
Wave length
Is the distance between two successive similar points in the wave
Wave length
Unit of measuring of Wave length is ..............
meter or cm
Is the number of vibrations in one second.
Frequency
Unit of measuring of frequency is ..............
hertz ( Hz ).
True or false : When an object vibrates faster, frequency of the sound wave increases.
True
It Is the height of the wave
Amplitude
Is the maximum displacement made by vibrating body away from starting position.
Amplitude
Unit of measuring of Amplitude
meter or cm
Determine amplitude from the figure
3 cm
Determine wave length from the figure
30/3 = 10cm
Determine the frequency from the figure
F = Wave # / t = 3 / 0.12 = 25 Hertz (Hz)
From characteristics of sound waves are ................ , ..................... , .................... & ................
