What is sound?

• Sound is a form of energy that does not require a medium to travel.

• Sound is a type of light wave.

• Sound is an electrical signal transmitted through wires.

• Sound is a mechanical wave caused by vibrating objects that travels through a medium.

How does sound travel?

• Sound travels faster in a vacuum than in air.

• Sound is a form of electromagnetic radiation.

• Sound travels through light waves.

• Sound travels through vibrations in a medium.

What is the speed of sound in air?

• 343 m/s

• 400 m/s

• 300 m/s

• 500 m/s

What are the three main properties of sound?

• Pitch, Volume, Echo

• Speed, Pressure, Density

• Rhythm, Harmony, Melody

• Frequency, Amplitude, Timbre

What is frequency in relation to sound?

• Frequency is the number of cycles per second of a sound wave, determining its pitch.

• Frequency is the speed at which sound travels through air.

• Frequency refers to the duration of a sound wave.

• Frequency is the loudness of a sound wave.

How does pitch relate to frequency?

• Pitch is unrelated to frequency; it is determined by volume.

• Frequency has no impact on the perception of pitch.

• Pitch is directly related to frequency; higher frequency means higher pitch.

• Higher pitch corresponds to lower frequency.

What is amplitude in sound waves?

• Amplitude is the frequency of sound waves, determining pitch.

• Amplitude is the maximum displacement of particles in a sound wave, indicating its loudness.

• Amplitude refers to the speed of sound waves in a medium.

• Amplitude is the distance between two sound waves, indicating their wavelength.

How does amplitude affect loudness?

• Higher amplitude results in louder sound, while lower amplitude results in softer sound.

• Lower amplitude leads to higher pitch.

• Loudness is unaffected by amplitude changes.

• Higher amplitude results in softer sound.

What is the difference between a sound wave and a light wave?

• Sound waves travel faster than light waves.

• Light waves require a medium to travel; sound waves do not.

• Sound waves can travel through a vacuum, while light waves cannot.

• Sound waves require a medium to travel; light waves do not.

What is resonance in sound?

• Resonance in sound is the reduction of sound waves when an object vibrates at any frequency.

• Resonance in sound is the distortion of sound waves when an object vibrates irregularly.

• Resonance in sound is the amplification of sound waves when an object vibrates at its natural frequency.

• Resonance in sound refers to the complete silence of sound waves in a medium.
