The physics
Wavelength is the physical distance between wave crests: wave speed divided by frequency. For light and radio, speed is the speed of light (299,792,458 m/s); for sound in air it's about 343 m/s.
Wavelength of 1 kHz sound in water (1,480 m/s)
Answer: wavelength = 1.48 m (wavelength 148 cm).
What we know
- Wave speed: 1480 m/s
- Frequency: 1 kHz = 1000 Hz (converted to the unit the formula takes)
Step by step
- Given
- v = 1480 m/s, f = 1000 Hz
- Formula
- λ = v / f
- Substitute
- λ = 1480 / 1000
- Result
- λ = 1.48 m
All results
| Wavelength | 1.48 m |
