Pressure

17
Q

The amount of a liquid normally measured in mL or L

A

Volume

18
Q

This equals mass divided by volume

A

Density

19
Q

Hydraulic machines work in accordance with this principle abor the pressure of fluids; when pressure is applied to a fluid it spreads throughout the fluid

A

20
Q

The upward force exerted by a fluid that helps an object float

A

Buoyancy

21
Q

When you squeeze the coils of a spring or slinky together you create this type of wave

A

Compressional

22
Q

The material that a wave is traveling through

A

Medium

23
Q

The distance from crest to crest or trough to trough on a transverse wave

A

Wavelength

24
Q

These type of waves have the ability to move through outer space

A

Transverse

25
Q

What type of waves are water waves or seismic waves

A

Both compressional and transverse

26
Q

This determines the height of the wave and the amount of energy a wave carries

A

Amplitude

27
Q

The number of wavelengths that pass a fixed point each sound; how often a wave occurs

A

Frequency

28
Q

This happens when 2 crest overlap or 2 troughs overlap producing a bigger wave

A

Constructive interference

29
Q

Lenses do this well; they bend light

A

Refeaction

30
Q

This will decrease if the intensity of a sound wave decreases

A

Loudness

31
Q

This happens when the crest of one wave crosses the trough of another wave

A

Destructive interference

32
Q

This will change if a waves travels from a less dense medium to a more senses medium

A

Wave speed

33
Q

This involves the bending and splitting of light waves into a rainbow

A

Diffraction

34
Q

Mirrors do this well; they take light waves and make them bounce back to create an image

A

Reflection
