Sound and Light Quiz

Relate frequency, wavelength, and amplitude of sound waves to pitch and loudness:

• Frequency affects pitch, and amplitude affects loudness.

• Wavelength affects loudness, and amplitude affects pitch.

• Frequency affects loudness, and wavelength affects pitch.

• Amplitude affects both pitch and loudness.

Sound waves travel faster through solids than through liquids because:

• Solids have a higher density than liquids.

• Solids have a more rigid structure than liquids.

• Solids have a lower density than liquids.

• Solids have a more flexible structure than liquids.
