  • P1 Key Vocab (Waves & the Universe)
    • TROUGH: lowest point of a wave
    • AMPLITUDE: maximum displacement of a wave from it's equilibrium position.
    • RAREFACTION: stretched out
    • COMPRESSION: close together
    • OSCILLATION: repeated disturbance
    • CREST/PEAK: highest point of a wave
    • WAVELENGTH: length of a single wave from one crest to another
    • FREQUENCY:no. of waves passing a fixed point per sec.
    • TIME PERIOD: time taken for wave to do a complete oscillation
    • NORMAL: a construction line perpendicular to reflective surface at point of incidence.
