Answer to Question #162081 in Physics for Romisa

Question

The shortest wave length emitted by bat about 3.3mm.what is corresponding frequency

Answer 1

We can find the frequency from the wave speed equation:

$$v=f\lambda,$$ $$f=\dfrac{v}{\lambda}=\dfrac{340\ \dfrac{m}{s}}{3.3\cdot10^{-3}}=103\ kHz.$$
