Indeed, the direction of displacement of a transverse wave traveling in a denser medium changes when it is reflected from the boundary of a rarer medium. The wave returns in the same phase as the incident wave, though, because there is no phase inversion upon reflection. The reflected wave’s displacement stays upward if the incident displacement was upward and downward if it was downward; only its direction is changed.

When the medium’s particles vibrate perpendicular to the direction of the wave’s propagation, the waves are said to be transverse. Light waves, water waves, and electromagnetic waves are a few types of transverse waves. In transverse waves, the points of greatest and least displacement from the equilibrium position are called crests (peaks) and troughs (valleys).

Nodes and antinodes make up stationary wave loops. Two consective antinodes (crest) or nodes (trough) are equal to one wavelength; the same is true for two consecutive crests or troughs. Therefore, when 10 cm is divided by the total length, n=4 (given), one wavelength, or 2.5 cm, is produced.

A vibration that travels through a medium, like air, water, or metals, is called a sound wave. “Inaudible sound with high frequency for human beings” is the definition of an ultrasonic wave, which typically has a frequency higher than 20 kHz. These days, an ultrasonic wave is another name for a sound wave that is not meant to be heard.
