Paper Rider

Slide the sonometer bridge until the paper rider jumps off. Match the wire to a tuning fork.

Physics · Class 11 · The sonometer · 6 simulations. For JEE, NEET and your boards.

What you'll learn

  1. Ring with the fork: Sonometer: f = (1/2l)√(T/μ)
  2. Move the bridge: Law of length: f × l stays fixed
  3. Two octaves up: Pitch and octaves: each octave doubles f
  4. A heavier load: Law of tension: f ∝ √T
  5. Match the thick wire: A thicker wire: μ = πr²ρ, so f ∝ 1/r
  6. Dip the load: A load in water: less tension, shorter gap
