## anonymous 4 years ago The shortest wavelength of the ultrasonic waves that a bat emits is 1.72mm.What is the frequency of these waves ? )Given the speed of sound in room temperature (22degrees in air) = 344 m/s. Answer needed urgently.Pl. help.

Let $$v$$ be the speed of the wave, $$f$$ the frequency and $$\lambda$$ the wavelength. Then it is true for all propagating waves such as sound that $v = f \lambda$ Use this equation, your values of $$v$$ and $$\lambda$$ to solve for frequency $$f$$.

Thank you James !Ramya

Use this same fundamental result for your other questions.
