Name two things that affect the speed of sound. Medium and temperature
why will sound travel the fastest through solids? Solid particles are closer together than any other medium.
Sound travels fastest at ________________ temperatures. High/Hot/warm
Why will sound travel faster at high temperatures? particles move more quickly and transfer energy faster.
Who will hear the sound LAST? a person under water, above water above
Sound waves interact with matter in 3 waves, name them. Reflection , absorption and transmission
Animals use reflected sound waves to find objects called? echolocation
What material will absorb sound the best? Soft material
What material will reflect sound the best. Smooth, hard surfaces
A reflected sound is called? Echo
What occurs when waves overlap and combine to form a wave with a larger amplitude or LOUDER sound. Constructive interference
What occurs when waves overlap and combine to form a wave with a smaller amplitude or SOFTER sound. Destructive interference
When two or more waves overlap and combine to form a new wave. interference
This occurs when a jet goes fast enough to break through the high pressure sound barrier that builds up in front of the plane. Sonic boom
When sound waves match the natural frequency of an object causing it to vibrate. Resonance
Considering all mediums, why do sound waves speed up or slow down? it all depends on the density of the medium or the speed at which the particles of the medium are moving.
when sound waves match the natural frequency of an object causing it to vibrate. Resonance
What is the relationship between frequency and wavelength? Inverse relationship (opposite)
