LUDO › Simulations › Wave Motion and Waves on a String

Pulse Race

Flick a rope and race the pulse against a stopwatch. Set the tension that makes it fast.

Physics · Class 11 · Pulse speed on a string · 7 simulations. For JEE, NEET and your boards.

What you'll learn

  1. The pulse, not the rope: A wave moves a shape, not the rope: t = L/v
  2. Tension sets the speed: Speed on a string: v = √(T/μ)
  3. Twice as heavy: Same speed on a heavier string: T grows with μ
  4. Climb the rope: A hanging rope: v = √(gx), so t = 2√(L/g)
  5. Rope in a lift: In a lift: g becomes g + a
  6. A block at the foot: A block at the foot: T = (M + μx)g
  7. The loop that stands still: A spinning loop: the pulse moves at ωR
