Wave Speed

Wave Speed

A wave has both frequency and spatial extent. The wavelength $lambda$ is the distance between successive crests. The wave equation connects all three quantities:

$v = flambda$

• v — wave speed (m/s)
• f — frequency (Hz)
• $lambda$ — wavelength (m)

Sound in Air

Sound travels at $approx 343$ m/s at 20 °C. This links frequency and wavelength for every audible tone:

Your Task

Implement waveSpeed(f, lambda) returning the wave speed in m/s.
