Pitch it
Pitch is the highness and _________ of sound,
lowness
All sound travels in ____________.
waves
Does a whistle has a high or low pitch/frequency?
high pitch/frequency
Does sound travel faster through cold air or hot air?
hot air
Tapping a glass full of water has the (same/different) rate of vibration than an empty glass of water.
different
Give an instrument that has a natural high pitch.
possible answers flute, piccolo
All sound is created by ____________.
vibrations
Slow vibrations have a (high/low) frequency.
low
Rank the rate of speed sound travels in the states of matter from fastest to slowest; gas, liquid, solid.
solid, liquid gas
Why does an empty gym echo whereas a gym full of people not echo?
The people/clothing absorb the sound waves.
A plucked long rubber band will have a (high/low) pitch compared to a short plucked rubber band.
low
Why is there no sound in space?
There are no air particles (atoms, molecules) to transmit the sound waves.
From lowest to highest, what is the sound frequency of these instruments; cello, violin, double bass?
double bass, cello, violin
What behavior of sound is similar to light reflecting off of an object?
echo
Why does sound travel faster through solids than liquids and gases?
the atoms/molecules are closer together so the sound waves can move along at a faster rate.
Why does a glass full of water have a lower pitch than an empty glass when you tap it?
The water in the glass slows the vibration of the glass.
A sound wave that has a high pitch, has a __________ frequency.
high
Why, as humans, can we not hear a dog whistle?
The frequency is too high for us to hear.
What happens to sound waves when they come into contact with a soft object?
they are absorbed by the object.
Why does sound travel faster through hotter air than colder air?
In the hotter air, the air particles are moving faster than the colder air particles so the sound wave can move along at a faster rate.
Give three properties (ways) in which pitch can change on a plucked string.
length, thickness, tension, density
A sound wave travels fastest through which property of matter AND temperature?
a HOT solid
Define sound frequency.
The rate of vibration.
If you pluck a rubber band harder and harder, what change is made to the sound?
It gets louder. (amplitude)
Does a longer or shorter tuning fork have a lower pitch? I gave you an easy question for 500 points...you are welcome.
longer
