How does the amplitude of a sound wave affect its volume?

• The volume of a sound wave is directly proportional to its amplitude.

• The volume of a sound wave is inversely proportional to its amplitude.

• The volume of a sound wave is not affected by its amplitude.

• The volume of a sound wave is proportional to its frequency, not its amplitude.

What is the difference between pitch and volume in sound waves?

• Pitch is related to amplitude, while volume is related to frequency.

• Pitch is related to wavelength, while volume is related to frequency.

• Pitch is related to speed, while volume is related to intensity.

• Pitch is related to frequency, while volume is related to amplitude.

What is an echo and how is it formed?

• An echo is a result of birds chirping

• An echo is formed by the wind blowing through trees

• An echo is created by the movement of clouds in the sky

• An echo is a reflection of sound waves that bounce off a surface and return to the listener's ears.

How does the density of a medium affect the speed of sound?

• Sound travels at the same speed in all mediums regardless of density.

• Sound travels slower in denser mediums.

• Density of a medium has no effect on the speed of sound.

• Sound travels faster in denser mediums.

Explain the concept of resonance in sound waves.

• Resonance is the complete absence of sound waves

• Resonance occurs when sound waves travel in a vacuum

• Resonance only happens at extremely low frequencies

• Resonance in sound waves is the phenomenon where an external force matches the natural frequency of an object, causing it to vibrate with increased amplitude, thus amplifying the sound produced.
