Question

a source is produce 50 compression and 50 rarefraction in 0.5 seconds find frequency​

Answer 1

$\huge \underline \green{\sf{ Answer :- }}$

• Frequency of wave is defined as the number of waves produced in 1 second. A longitudinal wave is formed by one compression and one rarefaction , we have 60 compressions and 60 rarefactions in 0.6s i.e. 60 waves produced in 0.6s ,

•   in 0.6s the number of wave produced =60

•    in 1s the number of wave produced =60/0.6=100Hz ,

• therefore , frequency f=100Hz

Answer 2

Answer:

Frequency of wave is defined as the number of waves produced in 1 second. A longitudinal wave is formed by one compression and one rarefaction , we have 60 compressions and 60 rarefactions in 0.6s i.e. 60 waves produced in 0.6s ,

in 0.6s the number of wave produced =60

in 1s the number of wave produced =60/0.6=100Hz ,

therefore , frequency f=100Hz
