Wavelength vs Wave Speed
公式
## Wavelength Wavelength is the spatial distance between two consecutive points of equal phase on a wave. ### Formula **lambda = v / f** Longer wavelengths correspond to lower frequencies when speed is constant.
计算示例
Concert A note (440 Hz) in air at 343 m/s.
- 01lambda = v / f
- 02lambda = 343 / 440
- 03lambda = 0.7795 m
- 04lambda = 77.95 cm
常见问题
What is the wavelength of visible light?
Visible light ranges from about 380 nm (violet) to 700 nm (red).
How does wavelength change when a wave enters a denser medium?
The wavelength decreases because the wave slows down while frequency remains constant.
What is the wavelength of a typical FM radio signal?
FM radio broadcasts around 100 MHz, giving a wavelength of about 3 meters.
