By the end, you can…

  • Explain Higher frequency → higher pitch · amplitude affects loudness
  • Change one input at a time and predict its effect before checking the model.
  • Apply the relationship in a quiz and explain the reasoning behind your answer.

Useful preparation: Units, measurement and proportional reasoning.

This topic has a suggested learning level. A matching chapter in the current NCERT edition has not been verified, so it is not labelled as syllabus coverage.

01 · How to explore

Make the idea your own

  1. 1Enable sound if you want to hear the demonstration.
  2. 2Keep amplitude fixed and compare two frequencies.
  3. 3Keep frequency fixed and change amplitude; inspect the speaker motion.

Explain the experiment

When the goal is met: The tone has 600 cycles per second. Frequency sets the repetition rate; amplitude changes signal strength. The visible vibration is slowed down.
