Mother dolphins whistle to their calves. This whistle works as a signature to help the calf identify its mother. If a mother dolphin whistles to its calf with a frequency of 15 kHz and a wavelength of 10 cm. What would be the speed of the sound wave of this whistle?

Question

Quizplus · Accepted Answer

To determine the speed of the wave, use the following equation:
V = f*λ where.
V = Speed
f = frequency
λ = wavelength
V = f*λ
V = (15,000 Hz)(0.1 m)
Speed = 1500 m/s
