Find the wave length of the given sound in a air its time period is equal to 0.02 sec and speed of sound in air 340 metre
Per/sec

Answers

Answered by neelbhatkar3

time period=0.02s

speed of sound V=340m/s

time period=1/f

0.02=1/f

f=1/0.02

f=100/2

f=50Hz

V=frequency x wavelength

wavelength=V/frequency

=340m/s / 50hz

wavelength=6.8m

atifali5254: Thanks a lot

neelbhatkar3: welcome:)

atifali5254: Lemda=c×1/f

neelbhatkar3: what?

neelbhatkar3: is there any doubt?

atifali5254: Lemda=c×1/f =Lemda=c×T=Lemda=340×0.02/100 =Lemda=6.8 ans This is right or not

neelbhatkar3: what is c here?

neelbhatkar3: it should be wavelength=340x100/2

atifali5254: what is c here?
Velocity

neelbhatkar3: bro time period=1/frequency and after finding frequency velocity=frequency x wavelength
