To calculate the frequency of a wave when the wavelength is given, you can use the formula:
frequency = speed / wavelength
The speed of a wave is typically denoted by the symbol "v" and represents how fast the wave is traveling. In the case of sound waves in air, the speed of sound is approximately 343 meters per second at room temperature.
Assuming you're referring to sound waves, with a given wavelength of 2 meters, you can plug the values into the formula:
frequency = 343 m/s / 2 m
Calculating this, the frequency would be:
frequency ≈ 171.5 Hz
So, if the wavelength of a sound wave is 2 meters, the frequency would be approximately 171.5 Hertz.
