1.

In a certain gas, a source produces 40,000 compression and 40,000 rarefaction pulses in 1 sec. When the second compression pulse is produced , the firsr is 1 cm away from the source. Calculate the wave speed?

Answer»

Solution :We know frequency is equal to number of COMPRESSION or rarefaction pulses TRAVELLED per SECOND, hence frequencey `(upsilon) = 40,000` Hz.
