Wave Behaviour (HSC SSCE Physics): Flashcards

Change in wave direction when entering new medium at angle

One part of wave speeds up/slows down before the other part

Stays the same

Changes proportionally

$v = f\lambda$

Speed & wavelength change, but NO direction change

Faster in warm air

Air higher up is warmer than air near ground

Sound waves refract downward toward ground in temp inversion

Line perpendicular to wave direction, all points same cycle
