4
Day 7

Spaced Revision

Come back to Sound Waves after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Waves transfer energy, not matter.
  • Amplitude relates to loudness, frequency to pitch.
  • Wave speed depends on the medium and is calculated as v = fλ.
  • Sound waves are longitudinal mechanical waves.
  • Transverse waves have perpendicular vibrations; longitudinal have parallel.
  • Standing waves do not travel and are formed by interference.
  • Progressive waves move energy forward.
  • Wave equation describes particle displacement.
  • Speed of sound is higher in solids than in gases.

Common Mistakes to Avoid

Sound waves are transverse because they move through air like ripples on water.

In a closed organ pipe, all harmonics (1st, 2nd, 3rd...) are possible.

The speed of sound increases with frequency or amplitude.

Memory Tips

Difference between transverse and longitudinal waves

Amplitude, Wavelength, Frequency, Speed of waves

Progressive wave equation: y(x,t) = A sin(kx ± ωt + φ)

Wave speed formula: v = fλ
