WebAll waves travel at different speed based on their wavelength. The wavelength (L) is calculated using: L = gT 2 /2π, where g=9.8 m/s 2 and T is wave period in seconds. The wave phase speed is calculated by the wavelength divided by wave period (just like the speed of your car is distance divided by time): speed = L/T
