Question

1. for a periodic wave, the displacement from the equilibrium point to the crest/trough of the wave is called the

a. wavelength
b. amplitude
c. frequency
d. period

Explanation:

• Wavelength: It is the distance between two consecutive crests or troughs.
• Amplitude: It is the maximum displacement from the equilibrium position (to the crest or trough).
• Frequency: It is the number of oscillations per unit time.
• Period: It is the time taken for one complete oscillation.

Answer:

B. Amplitude
