Sonar wavelength

  1. Dec 11, 2006 #1
    1. The problem statement, all variables and given/known data

    a bat operates on SONAR system at a frequency of about 50khz. Since SONAR only responds to targets larger than one wavelength in size, cant he bat detect mosquitos that are about 2mm in size?

    2. Relevant equations

    v= change in x/change in t

    3. The attempt at a solution

    for 50 KHz i find the wavelength to be 6.88 mm, so the bat will not detect the small 2mm mosquitos. is this correct?

    looks alright to me, but I'm not sure why you posted that equation. The one you need to use and it looks like you have is [tex]c=f\lambda[/tex]
