Physics · Ch. 7Sound Waves — Frequency & Pitch
Physics · Sound · Chapter 7
Longitudinal wave — needs a medium to travel.
f = 1/T — higher frequency, higher pitch.
v = f × λ ≈ 343 m/s in air.
As frequency rises, the same waveform compresses, producing a higher pitch. Doubling f raises the note by one octave.

The problem
Class moves fast. Your notes fall behind.
Live lectures demand your attention while every important word keeps moving.
Three tasks. One moment.
Listen. Understand. Write.Pick two.
Trying to do all three means one always loses—and class keeps moving.
