Understanding Sound Waves

What is the primary way sound waves move through a medium?

• By creating crests and troughs

• Through particle-to-particle interaction

• By moving physical matter

• Through electromagnetic fields

How is the frequency of a sound wave related to its pitch?

• Higher frequency means higher pitch

• Pitch is only affected by amplitude

• Frequency does not affect pitch

• Higher frequency means lower pitch

What is the audible range of human hearing in terms of frequency?

• 10 Hz to 10,000 Hz

• 100 Hz to 25,000 Hz

• 50 Hz to 15,000 Hz

• 20 Hz to 20,000 Hz

What does amplitude measure in a sound wave?

• The speed of the wave

• The wavelength of the wave

• The frequency of the wave

• The maximum displacement from rest position

How does a high amplitude sound wave affect perception?

• It is perceived as a low pitch sound

• It is perceived as a loud sound

• It is perceived as a high pitch sound

• It is perceived as a soft sound

What is the relationship between wavelength and frequency?

• They are directly proportional

• They both increase with amplitude

• They are inversely proportional

• They are unrelated

In which state of matter does sound travel the fastest?

• Gas

• Liquid

• Solid

• Plasma

What factor primarily affects the speed of sound in air?

• Wavelength

• Temperature

• Amplitude

• Frequency

What happens to the wavelength if the frequency of a wave is doubled?

• The wavelength doubles

• The wavelength quadruples

• The wavelength halves

• The wavelength remains the same

What remains constant when frequency changes in a uniform medium?

• Speed

• Wavelength

• Frequency

• Amplitude
