question 11 of 17
why was the tacoma bridge swaying?
○ wavelength
○ pitch
○ doppler effect
○ resonance

Explanation:

The Tacoma Narrows Bridge collapsed due to resonance, where wind-induced vibrations matched the bridge's natural resonant frequency, causing large, destructive swaying. The other options are unrelated: wavelength is a wave property, pitch is sound frequency, and the Doppler Effect is frequency shift from motion.

Answer:

Resonance
