A dolphin emits ultrasound at 100kHz and uses the timing of reflections to determine the position of objects in the water. What is the wavelength of this ultrasound? Assume that temperature of water is 20C.

Question

anonymous · Answer

velocity = frequency * wavelength
Use velocity of sound in water at the given temperature

shamim · Answer

u know the velocity of sound is  v
T= temperature in kelvin scale
then the relationship between v and T is

shamim · Answer

$$v  \alpha \sqrt{T}$$

shamim · Answer

so$$\frac{ v1 }{ v2 }=\sqrt{\frac{ T1 }{ T2 }}$$

shamim · Answer

here $$T1=293K, T2=273K, v2=332m/\sec ^{2}$$
