Question

for a wave, what term is defined as the distance between two successive crests or two successive troughs?

amplitude
wavelength
period
wave velocity
frequency

Explanation:

Identify the definition of wave properties

$$ \text{Distance between two successive crests or troughs} = \lambda = \text{wavelength} $$

Evaluate the given options

• Amplitude: Maximum displacement from equilibrium.
• Wavelength: Distance between successive identical points (crests/troughs).
• Period: Time for one complete cycle.
• Wave velocity: Speed of wave propagation.
• Frequency: Number of cycles per unit time.

Answer:

• amplitude
• wavelength (Correct answer)
• period
• wave velocity
• frequency
