What does the value 0.5 cm represent for the wave?

A. Amplitude
B. Wavelength
C. Equilibrium
D. Frequency

B. Wavelength

The value 0.5 cm does not represent any of the options given. The amplitude refers to the maximum displacement of a wave from its equilibrium position. The wavelength refers to the distance between two corresponding points on a wave, such as two adjacent peaks or troughs. The equilibrium is the resting or undisturbed position of a wave. Frequency, on the other hand, refers to the number of complete cycles of a wave that occur in a unit of time.
