Transverse waves exhibit a fascinating interplay between the movement of particles and the wave’s propagation. In such waves, particles oscillate perpendicular to the wave’s direction of travel, forming crests and troughs. The frequency of the wave determines the rate at which particles vibrate, while its wavelength governs the distance between successive crests or troughs. As … Read more
