Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
One student played high pitch notes and then low pitch notes on a guitar. What caused the difference in the high pitch and low pitch notes?
A
the age of the guitar strings
B
the color of the guitar strings
C
the material of the guitar strings
D
the vibrations of the guitar strings
Explanation: 

Detailed explanation-1: -Sounds are higher or lower in pitch according to the frequency of vibration of the sound waves producing them. A high frequency (e.g., 880 hertz [Hz; cycles per second]) is perceived as a high pitch and a low frequency (e.g., 55 Hz) as a low pitch.

Detailed explanation-2: -a thicker string has more tension than a thinner string and vibrates at a higher frequency.

Detailed explanation-3: -Guitar strings are tuned (tightened and loosened) using their tuning keys. Applying too much tension to a string tightly can raise it to the pitch of the next note, while loosening it can easily lower it the same amount. Increasing the tension raises the pitch.

Detailed explanation-4: -A guitar has strings of varying thickness but of the same material. The lighter string vibrates (faster) with higher frequency as compared to a thicker string. Hence, the thinner string has more shrillness in its sound than the thicker string.
