Question

The wavelength of a sound wave traveling under water with a speed of 1,470 m/s and a frequency of 2,340 Hz is?

1) 0.63 m
2) 0.62 m
3) 0.64 m
4) 0.65 m

Answer 1

The wavelength of a sound wave with a speed of 1,470 m/s and a frequency of 2,340 Hz is approximately 0.627 m. The closest answer is 0.63 m.

Step-by-step explanation:

The wavelength of a sound wave can be calculated using the formula: wavelength = velocity / frequency. Given the speed of sound underwater (1,470 m/s) and the frequency of the sound wave (2,340 Hz), we can calculate the wavelength as follows:

wavelength = 1,470 m/s / 2,340 Hz = 0.627 m

The closest answer to the calculated wavelength of 0.627 m is 0.63 m. Therefore, the correct answer is 1) 0.63 m.
