What Is Wave Length?
Wave length is the distance between two identical points in a wave cycle, such as crest to crest or trough to trough. It is commonly represented by the Greek symbol:
λ
Wave length is closely connected to frequency and wave speed.
The standard wave equation is:
v=λf
Where:
- v = wave speed
- λ = wavelength
- f = frequency
This formula is widely used in physics, acoustics, radio transmission, oceanography, and many other scientific fields.
