Question

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.

Answer 1

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 \( f \).
