Question

12 matching 2.5 points place the right word or number combination in the right phrase. the pitch of a note increases as the ___ increases sound is caused by ______ sound travels fastest through _ the range of frequency that can be detected by the human ear __ the loudness of the note increases as the ___ of the wave increases.

Explanation:

To solve this matching problem, we recall key concepts about sound from physics (Natural Science - Physics subfield):

1. "The pitch of a note increases as the \_\_\_ increases"

Pitch is related to frequency. Higher frequency means higher pitch. So the answer is frequency.

1. "Sound is caused by \_\_\_\_\_\_\_\_"

Sound is produced by vibrating objects (vibrations). So the answer is vibrations (of objects).

1. "Sound travels fastest through \_\_\_"

Sound travels fastest in solids (due to closer particle arrangement). So the answer is solids (e.g., metal, wood, etc.).

1. "the range of frequency that can be detected by the human ear \_\_\_"

The human audible range is typically \( 20 \, \text{Hz} \) to \( 20,000 \, \text{Hz} \) (or \( 20 \, \text{Hz} - 20 \, \text{kHz} \)). So the answer is is \( 20 \, \text{Hz} \) to \( 20,000 \, \text{Hz} \).

1. "The loudness of the note increases as the \_\_\_ of the wave increases"

Loudness is related to amplitude (energy of the wave). Larger amplitude means louder sound. So the answer is amplitude.

Final Matches:

• The pitch of a note increases as the \(\boldsymbol{\text{frequency}}\) increases.
• Sound is caused by \(\boldsymbol{\text{vibrations (of objects)}}\).
• Sound travels fastest through \(\boldsymbol{\text{solids}}\).
• The range of frequency that can be detected by the human ear \(\boldsymbol{\text{is } 20 \, \text{Hz} \text{ to } 20,000 \, \text{Hz}}\).
• The loudness of the note increases as the \(\boldsymbol{\text{amplitude}}\) of the wave increases.
