Lesson connection
Prepare for this practice
Sound begins with a vibration and reaches us through matter. Learn how wave frequency and amplitude relate to what we hear, and why the medium and surroundings change a sound.
Review Sound and waves before starting →Ideas to recall
- Sound is a mechanical wave produced by vibrations and requires a material medium.
- Frequency is measured in hertz and is closely related to perceived pitch.
- Greater wave amplitude usually means greater intensity, though perceived loudness is also affected by the ear and frequency.
- Sound can reflect, be absorbed, or change speed as it travels through different materials.
Use these ideas to reason through each question; answer-specific explanations appear only after you check a response.
