Sound

What type of wave does sound travel as?

• Electromagnetic

• Transverse

• Longitudinal

• Radio

How is all sound created?

• By humans

• By vibrations

• By Earth's magnetic field

• By gravity on Earth

Why is Sound not able to travel through space?

• The gravity of the sun is too strong.

• Sound needs Earth's magnetic poles to be able to travel.

• There is no medium (air) for sound to travel on.

• For sound to work you need to be standing on something solid.

From SLOWEST to FASTEST, which is the order Sound waves would travel through?

• Liquid, Solid, Gas

• Gas, Liquid, Solid

• Solids, Gas, Liquids

• Solid, Liquid, Gas

What is the ability of a material to bounce back after being disturbed?

• Density

• Refraction

• Temperature

• Elasticity

The speed of Sound is equal to __________

• 343 meters per second

• 25 inches per second

• 100 miles per hour

• 1 foot per minute

What is EQUAL to the mass or amount of matter, there is in a given space, or volume?

• Elasticity

• Speed

• Density

• Temperature

How does Temperature affect the speed of sound?

• The colder a medium is the faster sound travels

• The warmer a medium is the slower sound travels

• The colder the medium is the slower sound travels

• Temperature has no affect on the speed of sound

What is an echo?

• A sound wave that interferes with another sound wave

• A refracted sound wave

• A sound wave that diffracts through a barrier

• A reflected sound wave

What type of sound wave interaction makes noise cancelling head phones work?

• Reflection

• Diffraction

• Constructive Interference

• Destructive Interference
