← ScienceWhich acoustic phenomenon occurs when tuning forks excite resonance?
A)Constructive wave interference amplifies the sound✓
B)Destructive interference negates all vibrations
C)Diffraction bends the sound waves inward
D)Refraction aligns waves out of phase
💡 Explanation
Constructive interference amplifies resonant frequencies because sound waves align in phase, rather than canceling each other out. Therefore, higher sound intensity emanates from overlapping waves, rather than destructive cancellation or merely wave bending.
