Bats and High Frequencies

  1. Apr 22, 2009 #1
    1. The problem statement, all variables and given/known data
    Why can animals such as bats, that have tiny, light-weight ear parts, hear sounds with much higher frequencies than humans can hear?

    2. Relevant equations
    written response

    3. The attempt at a solution
    Waves with low frequencies are smaller than those with high, so they can therefore move the small parts of the bats ear?

    What do you mean by "smaller"? I'm guessing you mean amplitude... which relates to loudness, not pitch.

    Hint: perhaps think about why a wineglass might be susceptible to breaking at certain frequencies.
