Question

You are at the edge of a cliff. You whistle and hear your echo in 2.5 seconds. Assume the speed of sound at that location is 340 m/s and the frequency of your whistle was 680 Hz. What is the wavelength of your whistle at that location?

a) 0.25 meters
b) 0.50 meters
c) 0.75 meters
d) 1.00 meter

Answer 1

The wavelength of the whistle at the edge of the cliff, with a frequency of 680 Hz and a speed of sound of 340 m/s, is 0.50 meters.

Step-by-step explanation:

The question asks to determine the wavelength of a whistle given the frequency and the speed of sound. To calculate the wavelength of a sound wave, you can use the formula λ = v / f, where λ is the wavelength, v is the speed of sound, and f is the frequency of the sound wave.

In this scenario, the speed of sound at the location is given as 340 m/s, and the frequency of the whistle is 680 Hz. Applying the formula results in: λ = 340 m/s / 680 Hz = 0.50 meters. Therefore, the correct answer is b) 0.50 meters.
