šŸ”Š Doppler Effect

Observe how sound wave frequency changes when the source is moving relative to an observer

Difficulty: ā— Easy

šŸ“ Physics Formulas
f' = f Ā· (v Ā± vā‚€) / (v Ā± vā‚›)
Observed frequency formula
Ī» = v / f
Wavelength relationship
Mach Number = vā‚› / v
When Mach ā‰„ 1: Sonic boom!
šŸ“š Key Concepts
  • Waves bunch up in front of moving source
  • Waves spread out behind moving source
  • Observer hears higher pitch when source approaches
  • Observer hears lower pitch when source recedes
  • At supersonic speeds, shock waves form
šŸ”¬ Try This
  • Start slow and gradually increase speed
  • Watch wave compression as speed increases
  • Push velocity to supersonic (>343 m/s)
  • Observe the V-shaped shock wave pattern
  • Compare subsonic vs supersonic behavior
