Physics 112 Quiz 1 Ch 16

physics 112 quiz 1 ch 16

This quiz covers acoustics topics in physics, exploring sound frequency, wavelength, sound speed in different environments, and resonance in musical instruments.

Questions: 9 | Attempts: 103 | Last updated: Jan 22, 2025

Sample Question
A source emits a sound of constant frequency, f. If this sound enters an environment where the speed of sound is greater f stays the same and:

Lambda becomes longer.

Lambda becomes shorter.

Lambda stays the same if f is unchanged.

No. the speed of sound is a "constant" so f must change along with lambda.

No. the speed of sound, wavelength and frequency will all be unchanged.
