Q

Does the thickness of a material have anything to do with the pitch?

A

Yes! Changing the thickness of a material can change the pitch of the sound.

Q

Thicker materials vibrate more slowly. How does this affect the pitch?

A

Thicker materials vibrate slower, so the pitch is lower.

For example, a thicker person is going to run a race more slowly. So, they are going to place lower at the end of the race when compared to people that ran quicker.

Q

Thinner materials vibrate faster. How does this affect the pitch?

A

Thinner materials vibrate faster, so the pitch is higher.

For example, a thinner person is going to run a race faster. So, they are going to place higher at the end of the race when compared to people that ran slower.

Q

When the length of a vibrating material is changed, what happens?

A

The pitch changes too! If you stretch a material out it is going to make it thinner! If you scrunch a material up, it is going to make it thicker!

Q

If you increase the tension of a material, what happens to the vibration and the pitch?

A

When you increase the tension, the material vibrate faster and the pitch is higher.

Q

If you decrease the tension of a material. what happens to the vibration and the pitch?

A

When you decrease the tension, the material vibrates slower and the pitch is lower.

Q

If more force is put on a material, what happens to the vibrations and the volume?

A

If you put more force on a material then it produces stronger vibrations and a louder volume.

Q

If less force is put on a material, what happens to the vibrations and the volume?

A

If you put less force on a material then it produces weaker/slower vibrations and a quieter volume.

17
Q

How does distance affect volume and sound?

A

The greater the distance between the source of the sound vibrations, the softer the volume is and the quieter the sound is!
