Wave Parameters
The Wave Equation
The wave equation describes the relationship between the speed, frequency, and wavelength of a wave. It is a fundamental concept in physics, applicable to all types of waves, including sound waves, light waves, and water waves.
This equation can be rearranged to solve for any of the three variables:
- Frequency: f = v / λ
- Wavelength: λ = v / f
- Wave Speed: v = f × λ
Where:
- v = Wave speed (m/s)
- f = Frequency (Hz)
- λ = Wavelength (m)
Wave Examples
| Wave Type | Speed (m/s) | Frequency (Hz) | Wavelength (m) |
|---|---|---|---|
| Sound in Air | 343 | 440 | 0.78 |
| Light in Vacuum | 3 × 108 | 5 × 1014 | 6 × 10-7 |
| Ocean Wave | 5 | 0.2 | 25 |
Frequently Asked Questions
What is a wave?
A wave is a disturbance that transfers energy through a medium or space without necessarily transferring matter. Examples include sound waves, light waves, and water waves.
What is the wave equation?
The fundamental wave equation relates wave speed (v), frequency (f), and wavelength (λ): v = f × λ. This equation is applicable to all types of waves.
What are the key properties of a wave?
The key properties of a wave are: Wavelength (λ), the distance between two consecutive corresponding points on a wave; Frequency (f), the number of wave cycles passing a point per unit time; and Wave Speed (v), how fast the wave propagates through a medium.
