Formula:
* Speed (v) = Wavelength (λ) * Frequency (f)
Units:
* Wavelength (λ): Usually measured in meters (m), centimeters (cm), or millimeters (mm).
* Frequency (f): Usually measured in Hertz (Hz), which represents cycles per second. Kilohertz (kHz) is 1000 Hertz.
* Speed (v): Measured in meters per second (m/s), centimeters per second (cm/s), or millimeters per second (mm/s).
Example:
Let's say you have a wave with:
* Wavelength (λ) = 5 cm
* Frequency (f) = 2 kHz (which is 2000 Hz)
Calculation:
1. Convert the wavelength to meters: 5 cm = 0.05 m
2. Calculate the speed: v = 0.05 m * 2000 Hz = 100 m/s
Therefore, the speed of the wave is 100 meters per second.
Important Note: Make sure your units are consistent before you do the calculation. If your wavelength is in centimeters, your frequency should be in Hertz (not kHz).
