Can anyone tell me the difference between logitudinal and transverse wave?
Could we actaully tell the difference from their given wave equation?

A longitudinal wave is a type of wave in which the particles of the medium vibrate in the same direction as the wave travels. This means that the disturbance of the particles is parallel to the direction of the wave. In contrast, a transverse wave is a type of wave in which the particles of the medium vibrate perpendicular to the direction of the wave. This means that the disturbance of the particles is at right angles to the direction of the wave.
Sound waves are classified as longitudinal waves because they travel by compressing and expanding the particles of the medium in the same direction as the wave travels. This means that the particles vibrate back and forth along the same axis as the wave, making sound waves a type of longitudinal wave.
Examples of transverse waves include electromagnetic waves such as light and radio waves, as well as water waves and seismic S-waves. These waves all have their particles oscillating perpendicular to the direction of the wave.
Sound waves require a medium to travel through, such as air or water. This is because sound waves are longitudinal waves, and they need particles to vibrate in order to propagate through a medium. In a vacuum, there are no particles for sound waves to interact with, so they cannot travel.
The speed and wavelength of a wave are inversely proportional. This means that as the wavelength increases, the speed of the wave decreases, and vice versa. This relationship is described by the wave equation: speed = frequency x wavelength.
