The derivation of the wave equation certainly varies depending on context. Derivation of the Formula lambda l refers to the wavelength the distance between the crests in meters m v refers to the velocity of the speed of waves are moving in a direction in meter per seconds ms f refers to the frequency the wave crests that go through a point in certain time cycles per second or hertz cycless or Hz. 5 1 0 1 0 N m 2.
2600 kgm 3 2600kgm3 and Youngs modulus.
More step by step of my work. Reversing it you can say that the wavelength is approximately the square of the wave speed divided by 1249. The unit from the formula is Hz but you can also input KHz. Therefore the wave period is 00005 seconds.
