Reflection, Diffraction and Resonance of Sound Waves (HSC SSCE Physics): Flashcards

Reflect it

Absorb it

Reflection arriving ≤0.1s, heard as prolonged sound

≤17 m

Reflection arriving >0.1s, heard as separate sound

17 m

Wave spreading through opening or around obstacle

$v = f\lambda$

$340 \text{ m} \cdot \text{s}^{-1}$

Wavelengths (several m) comparable to doorway size (~1 m)
