Rules for naming compounds:
Mono=One(skipped if it's the first atom),
Di=2, Tri=3, Tetra=4.
Usually skip double vowels, e.g. monooxide=monoxide.
Change the ending of the last element, often to -ide.

1 carbon, 1 oxygen
1 carbon, 2 oxygen
1 carbon, 3 oxygen
2 carbon, 2 oxygen

Sound is caused by a...
Sound
Wave
Vibration
Noise
What are each of these waves called?
Top = Longitudinal. Bottom = Transverse.
Top = Transverse. Bottom = Longitudinal.
Both = Transverse
Both = Longitudinal
Which wave is more a accurate diagram of a sound wave?
Top, the bottom is just easier to draw.
Bottom, that's why we usually draw them like that.
Neither, that's why I'm asking a silly question.
If a sound wave is louder, we say it has a greater...
Frequency
Wavespeed
Wavelength
Amplitude
The wavelength is the distance between...
Two crests
Two troughs
Amplitudes
Any equivalent points on the waves
A lower pitched sound has more spaced out sound waves. This means it has...
A greater amplitude
A greater wavelength
A greater frequency
All of the above
The number of waves per second, or how many full times the wave goes up and down, back to its starting position, is called its...
Period
Time
Frequency
Often-ness

300,000,000 meters per second
How fast (roughly) is the speed of a light wave?
5 meters per second
10 meters per second
300 meters per second
300,000 meters per second
300,000,000 meters per second
If I changed my voice to be louder and squeaky(high frequency), the sound waves would be...

What do we measure LOUDNESS and FREQUENCY in? (What are the units!?)
Loudness = Hurts, Frequency = Hertz
Loudness = Decibels, Frequency = Bels
Loudness = Hurts, Frequency = Pitch
Loudness = Decibels, Frequency = Hertz
What frequency sound can humans hear?
One Hertz (Hz) = The wave goes one full up and down per second.
Two Hertz = TWO full waves per second. etc.
1 Hertz and higher
Between 1 and 10,000 Hertz
Anything under 1 Hertz isn't painful
Between 20 and 20,000 Hertz
