🔧 Using the Wave Equation
Rearrangements:
- v = f × λ (find speed)
- f = v / λ (find frequency)
- λ = v / f (find wavelength)
Key relationships:
- Higher frequency → 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 × λ = 5 × 2 = 10 m/s
Practice questions for Wave Properties
What do waves transfer from one place to another?
Explain the difference between a transverse wave and a longitudinal wave.
Quick recall flashcards
Wave equation
v = fλ (wave speed = frequency × wavelength)
What is amplitude?
Maximum displacement from rest position (determines energy/loudness/brightness)
