of the wave, respectively; further,

represents the wavelength associated with the wave We had discussed
propagation of such waves in Chapter 14 of Class XI textbook Since the
displacement (which is along the y direction) is at right angles to the
direction of propagation of the wave, we have what is known as a
transverse wave
