18
Q

Frequency

A

The number of waves that pass a given point in one second

19
Q

Loudness

A

How loud or quiet something is

20
Q

Longitudinal Waves

A

Vibrations occur in the same direction as the direction of energy transfer

21
Q

What do all types of waves have?

22
Q

What is the unit for frequency?

23
Q

What does 10 hz mean, for example?

A

Ten vibrations per second

24
Q

Inversely proportional

A

When one variable doubles, the other halves.

25
Does the frequency affect the amplitude?
No
26
Superposition
What happens after two waves meet after approaching each other
27
Convection
Heat rises and as it does it cools down, continues this cycle
28
Thermal Equilibrium
When everything is the same temp.
29
Conduction
Heat transfer of diff particle
