Question

What are the three parts of sound? (Select all that apply.)

the detection of sound

the energy source

the transfer of energy through a medium

the identification of pitch

Answer 1

The three parts of sound typically include:

1. **The energy source** - This is what produces the sound waves (e.g., a vibrating string, vocal cords, etc.).
2. **The transfer of energy through a medium** - Sound requires a medium (like air, water, or solids) to travel.
3. **The detection of sound** - This refers to how sound is received by our ears or other devices.

The identification of pitch is related to the perception of sound but is not considered a fundamental part of sound itself. Therefore, the correct selections are:

- The energy source
- The transfer of energy through a medium
- The detection of sound
