Detailed Solution
Download Solution PDFThe Correct answer is Speed = Frequency × Wavelength.
Key Points
- The formula Speed = Frequency × Wavelength is fundamental to understanding wave physics.
- The speed of a wave refers to how fast the wave propagates through a medium.
- Frequency is the number of wave cycles that pass a given point per second, measured in Hertz (Hz).
- The wavelength is the distance between two consecutive points of similar phase on the wave, such as crest to crest, measured in meters (m).
- This relationship is derived from the fact that the speed of a wave is the distance a wave travels per unit of time.
- The formula is applicable to various types of waves, including sound waves, light waves, and water waves.
- For light waves in a vacuum, the speed is constant and equals the speed of light, approximately 3 × 108 m/s.
- The formula is crucial for calculations in fields such as optics, acoustics, and electromagnetic wave theory.
