Question

Difficulty: EasyWaves, Sound, and Light

Waves transmit energy through space and matter and are described by specific physical characteristics. How should each wave property on the left be paired with its correct definition on the right?

  • AmplitudeThe maximum displacement of a vibrating particle from its rest or equilibrium position
  • FrequencyThe number of complete wave cycles that pass a given point per unit of time
  • WavelengthThe spatial distance between two successive crests or troughs of a wave
  • PeriodThe amount of time required to complete one full wave cycle

Answer

Amplitude pairs with maximum displacement from rest position; Frequency pairs with number of cycles per unit time; Wavelength pairs with distance between successive crests or troughs; Period pairs with time required for one full wave cycle.
Each term is accurately matched to its standard physical definition: amplitude describes height from rest position, frequency measures cycles per second, wavelength measures physical distance between peaks, and period measures the duration of one cycle.

Step-by-Step Solution

1
Identify spatial wave dimensions
Amplitude corresponds to displacement height from equilibrium, while wavelength is the linear distance between identical points on consecutive waves.
Separating vertical displacement from horizontal spatial extent clarifies the two geometric dimensions of a wave.
2
Identify temporal wave characteristics
Frequency measures cycle count per second (rate), while period measures total time per cycle (duration).
Frequency (ff) and period (TT) are reciprocal properties related by f=1Tf = \frac{1}{T}.

Key Concept

Fundamental wave parameters (amplitude, frequency, wavelength, and period) define the spatial and temporal behavior of waves.
