A bat can hear a sound of frequency up to 18000 Hz. Determine the minimum wavelength of the sound which it can hear. ( speed of sound in air is 340 m s−1 ). Immediate solution will be appreciated. have got a test tomorrow morning. Share with your friends Share 0 Rohit Babu answered this Dear Student,Given,f=18000Hz,V=340m/sWe have,Velocity=Frequency×WavelengthV=fλ⇒Wavelength of the sound heard by bat is,λ=Vf=34018000=3418×102=1.88×10-2mRegards. 0 View Full Answer
