Bill Nye: Sound Questions and Answers
| 2024/2025 | 100% Pass
What is sound?


✔✔ Sound is a form of energy that travels in waves through a medium, such as air, water, or

solid materials.




How do sound waves travel?


✔✔ Sound waves travel as vibrations that move through a medium, causing particles in the

medium to oscillate and transmit the energy.




What is the difference between pitch and volume?


✔✔ Pitch refers to the frequency of a sound wave, determining how high or low a sound is,

while volume refers to the amplitude of the sound wave, determining how loud or soft the sound

is.




What determines the pitch of a sound?


✔✔ The pitch of a sound is determined by the frequency of the sound wave; higher frequencies

result in higher pitches, and lower frequencies result in lower pitches.

, How does the medium affect the speed of sound?


✔✔ The speed of sound varies depending on the medium; it travels faster in solids than in

liquids, and faster in liquids than in gases due to the density and elasticity of the medium.




What is the Doppler effect?


✔✔ The Doppler effect is the change in frequency or wavelength of a sound wave as the source

of the sound moves relative to an observer, causing a perceived change in pitch.




What is resonance?


✔✔ Resonance occurs when an object vibrates at its natural frequency due to external vibrations,

amplifying the sound.




How do our ears perceive sound?


✔✔ Our ears perceive sound through the outer ear collecting sound waves, which then travel

through the ear canal to the eardrum, causing it to vibrate and transmit these vibrations to the

inner ear.




What role does frequency play in sound quality?
