🎓 Higher Tier Only: Period and Frequency
Period (T) and frequency (f) are reciprocals of each other:
T = 1/f and f = 1/T
For example, a wave with frequency 50 Hz has a period of 1/50 = 0.02 s (it completes one full oscillation every 0.02 seconds). This relationship is important when interpreting oscilloscope traces — the horizontal scale gives you period, from which you can calculate frequency.
Quick Check: Is sound a transverse or longitudinal wave? How do you know?
Sound is a longitudinal wave. Air molecules vibrate parallel to the direction the sound travels, creating compressions and rarefactions. It cannot be transverse because air cannot support sideways (shear) vibrations.
