Answer:
0.29 meters, or 29 centimeters.
Step-by-step explanation:
The wavelength of a sound wave is related to its frequency and the speed at which it travels. The relationship between these quantities is given by the equation:
wavelength = speed / frequency
Plugging in the values given, we get:
wavelength = 345 m/s / 1200 Hz
This gives us a wavelength of approximately 0.29 meters, or 29 centimeters.
It's important to note that this is an approximate value, as the speed of sound can vary depending on the temperature, humidity, and other factors of the air through which it is traveling.
