Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 2.
Key Points
- The frequency (f) of a wave is the reciprocal of its period (T).
- The formula to calculate frequency is f = 1/T.
- Given the period T = 0.04 seconds, applying the formula gives f = 1/0.04.
- Therefore, the frequency of the wave is f = 25 Hz.
Additional Information
- Frequency (f):
- Frequency is the number of complete wave cycles that pass a point per unit of time, typically measured in Hertz (Hz).
- 1 Hz is equal to one cycle per second.
- Period (T):
- The period is the time taken for one complete cycle of the wave to pass a given point.
- It is usually measured in seconds (s).
- Relationship between Period and Frequency:
- The period is the inverse of the frequency: T = 1/f.
- Similarly, frequency is the inverse of the period: f = 1/T.
- Wave Cycles:
- A wave cycle consists of one complete wave oscillation, typically measured from crest to crest or trough to trough.
