1.Sound is a form of energy made by ____________
electricity
vibration
light
volume
Sound waves cannot travel in __________.
air
steel
water
a vacuum
What is the best explanation for why sound travels faster in air at 45 °C than at 0 °C?
Warm air particles have less energy and vibrate more slowly.
Warm air particles have more energy and can vibrate faster.
Cold air particles have more energy and can vibrate faster.
Cold air particles have more energy and vibrate more slowly
Why does sound travel slower through gases (air) than through liquids (water) or solids (gold and glass)?
Particles in gases are closer together than particles in liquids and solids.
Gas particles have less energy than particles in liquids and solids.
Particles in gases are further apart than particles in liquids and solids.
Gas particles transfer energy better than particles in liquids and solids
What is Pitch?
How loud or soft a sound is.
Muscle that holds vocal cords.
Movement back and forth.
How high or low a sound is.
__________ is the loudness or softness of a sound.
The volume of a sound is measured in units called ________
decibels
hertz
frequency
amplitude
Which of the following sound wave produces the highest pitch of sound?
Frequency is measured in the unit of
Ampere (A)
Hertz (Hz)
Mole (mol)
Meter (m)
Which of the following statement is true?
The higher the amplitude, the higher the pitch of sound
The lower the amplitude, the louder the sound
The higher the frequency, the higher the pitch
The lower the frequency, the louder the sound
What is a sound that is repeated because the sound waves are reflected back?
Pitch
Echo
Vibration
Volume
