Adolphin emits ultrasound at 100khz and uses the timing of reflections to determine the position of objects in the water. part a what is the wavelength of this ultrasound? assume that temperature of water is 20 degrees c. answer in cm

1.53 cm

Explanation:

The relationship between wavelength and frequency for a wave is:

where

v is the speed of the wave

f is the frequency

is the wavelength

In this problem, we have:

is the frequency of the ultrasound wave

is the speed of sound in sea water at room temperature

Re-arranging the previous equation and solving for , we find the wavelength of the ultrasound wave:

if they have a finite resultant

i believe the answer is a hope it and is correct
