as a longitudinal wave
4
Q

A
Hertz or kilohertz
8
Q
How can you see sound
A
By plugging your microphone into an oscilloscope.
9
Q
How does the oscilloscope present your voice
A
In a transverse wave
10
Q
What happens when a sound is loud
A
The vibrations are bigger
The wave has a bigger amplitude
It transfers more energy
11
Q
What happens when sound deflects off a surface
A
It makes an echo
12
Q
How do you find the distance of a sound
A
Distance=(speed of sound*time delay)/2
