Detailed explanation-1: -Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.
Detailed explanation-2: -Velocity = Wavelength x Frequency EXAMPLE: A wave as a Wavelength of 5 meters and a Frequency of 10 Hz. What is its velocity? V = 5 x 10 → V= 50 meters per second Solve using the wave velocity equation: (Show your equation set up and math work) 1-A wave has a Wavelength of 12 meters and a Frequency of 10 Hz.
Detailed explanation-3: -∴ Wavelength of the wave =v=510=2 m.
Detailed explanation-4: -Multiply the wavelength in meters with frequency in hertz. You will get the wave speed in m/s. Congrats! You have calculated wave speed from frequency and wavelength. 02-Feb-2023
