Question

A single frequency sound wave is emitted by a loud speaker in the Hebb theater. If the frequency of the sound wave if 1000Hz, what is its wavelength? (Pick the closest answer)

A. 1.0 m
B. 0.5 m
C. 0.2 m
D. 0.1 m

Answer 1

The wavelength of a sound wave can be calculated using the formula wavelength = speed / frequency. With a sound wave frequency of 1000 Hz and a speed of sound in air of 343 m/s, the wavelength would be approximately 0.3 m.

Step-by-step explanation:

To calculate the wavelength of a sound wave, we can use the formula:

wavelength = speed / frequency

Given a frequency of 1000 Hz, we need to determine the speed of sound in order to find the wavelength. In air, the speed of sound is approximately 343 meters per second. Plugging in these values:

wavelength = 343 m/s / 1000 Hz = 0.343 m = 0.3 m

So the closest answer choice is 0.5 m.
