Use the information below to solve this problem: A note has a wavelength of 0.65551 m. If the speed of sound is 343.00 m/s, what pitch is this note? information below shows v=fa

f=v/a

a=v/f

speed of sound in the air

Your target variable is δf, the magnitude of the difference in frequency between the waves emitted from the sonar device and the waves received by the device after reflecting off the whale. write an expression for δf in terms of the relevant frequencies using the subscript notation introduced above.
