V flambda This is when. The wave equation is a very important formula that is often used to help us describe waves in more detail. A wave traveling along the x axis is described mathematically by the equation y 015 sin 85p t - 053p x where y is the displacement in meters t is in seconds and x is in meters.
Where v is the velocity of the wave.
The amplitude phi and the cos portion of the partial derivatives would all cancel out. T of a time variable t and one or more spatial variables x1 x2 xn. Speed frequency x wavelength 3. Wave Speed Formula The following formula is used to calculate the speed or velocity of a wave.
