How often a wave cycle is completed is referred to as Amplitude (b) wavelength (d)period (e)frequency
Question
How often a wave cycle is completed is referred to as:
- (a) Amplitude
- (b) Wavelength
- (c) Period
- (d) Frequency
Answer
The correct answer is Frequency.
Detailed Explanation
Frequency describes how often a complete wave cycle occurs per unit time.
It is calculated as the reciprocal of the Period, which is the time taken for one complete cycle. Mathematically:
Frequency (f) = 1 / Period (T)
Frequency is measured in Hertz (Hz), which indicates the number of cycles occurring every second.
Key Terms to Differentiate
- Amplitude: The maximum displacement of points on a wave, related to the wave’s energy or intensity.
- Wavelength: The distance between two consecutive crests or troughs of a wave.
- Period: The time required for one full cycle to occur.
- Frequency: The number of complete cycles per second (how often the cycle repeats).
Therefore, when asked “How often a wave cycle is completed,” the precise term is Frequency.
