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

Question

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
