9sci sound waves

Draw a wave and label wavelength and amplitude

What causes sound waves to form?

• vibrating objects

• magnetic objects

• the sun

• heat energy

What is the part of a sound wave where the particles are bunched up (compressed)?

• Compression

• Rarefaction

• Tight

• Transverse

What is the part of a sound wave where the particles are spread apart?

• Compression

• Rarefaction

• Loose

• Transverse

Why can't sound travel through space?

• No particles present to vibrate and "knock" other particles to transfer energy

• Too many particles in space, sound vibrations get all mixed up together and pulled in by gravity

• Sound can't travel through space because it is too slow
• Sound can't travel through space because it is too heavy

Sound travels _______ through mediums which are more dense (particles closer together)

• faster

• slower

• inside

• outside

Reorder the following from the material would which transmit sound the slowest to the fastest

• Liquid

• Solid

• Gas

• B

• C

• D

• E

Which letter represents a trough?

• A

• B

• C

• D

• E

The distance from one point to the next corresponding point on a wave is called the ________________.

• waveform

• peak

• amplitude

• wavelength
