Rearrangements:
- v = f Ă Îť (find speed)
- f = v / Îť (find frequency)
- Îť = v / f (find wavelength)
Key relationships:
- Higher frequency â shorter wavelength (for same speed)
- Speed depends on the MEDIUM, not the wave itself
- Frequency is set by the SOURCE and doesn't change
Quick Check: A wave has a frequency of 5 Hz and a wavelength of 2 m. What is its speed?
v = f Ă Îť = 5 Ă 2 = 10 m/s
