Question 1

What are Sound Waves?

Answer 1

These are longitudinal waves that are created with the vibration of particles and can be reflected and refracted.

Question 2

What is the Human Audible Frequency Range?

Answer 2

20Hz - 20,000Hz

Question 3

What is the name given to sounds with a frequency below 20Hz

Answer 3

Infrasound

Question 4

What is the name given to sound with a frequency above 20,000Hz

Answer 4

Ultrasound

Question 5

What is the Frequency

Answer 5

This is the number of vibrations that happen per second.

Question 6

How to get a more accurate reading for the speed of sound

Answer 6

Using Echoes instead of a sound that goes straight.

Question 7

How does the Pitch of a sound relate to the Frequency

Answer 7

As the frequency increases, the pitch of the sound will also increase.

As the frequency decreases, the pitch of the sound will also decrease.

Question 8

How does the loudness of a sound relate to the amplitude of a sound wave

Answer 8

As the amplitude increases, the loudness also increases.

As the amplitude decreases, the loudness also decreases.

Question 9

Why can’t sound waves travel through a Vaccum

Answer 9

Because a vacuum does not have any particles to carry the sound wave through vibrations.
