1.	Question : Define amplitude,time period and frequency of sound wave.
Answer» Solution :AMPLITUDE : The magnitude of the maximum disturbancein the medium on EITHER side of the mean value is called amplitude of THEWAVE. Its unit is meter. Time period : The time taken by two consecutivecompression. or RAREFRACTION to cross a fixed point is called the time period of the WAVE. Frequency : The number of oscillation, occurring per unit time is called the frequency of sound wave.
