Explanations: answer key for all 10 questions

Q1: What creates sound?
Answer: Vibrations
A vibrating object pushes air particles, creating waves.
Q2: Why is there no sound in space?
Answer: There is no air to carry it
Sound needs a medium like air, water or solids.
Q3: About how fast does sound travel in air at room temperature?
Answer: About 343 meters per second
It travels faster in water and steel.
Q4: What property of a sound wave determines pitch?
Answer: Frequency
Higher frequency means higher pitch.
Q5: What is loudness measured in?
Answer: Decibels
Every 10 decibels is about ten times more intense.
Q6: What is the typical range of human hearing?
Answer: About 20 to 20,000 hertz
The upper limit drops with age.
Q7: What is an echo?
Answer: Reflected sound
Bats use echoes to find prey.
Q8: What causes a sonic boom?
Answer: An object moving faster than sound
Shock waves build up and release.
Q9: What is ultrasound?
Answer: Sound above human hearing range
It is used in medical imaging.
Q10: Which animals communicate with very low infrasound over long distances?
Answer: Elephants and whales
Infrasound travels far.

Sound Waves Trivia – Waves You Can Hear

Sound is a wave of vibrations traveling through air, water or solids. When a guitar string or vocal cords vibrate, they push nearby particles, creating regions of compression and expansion that move outward until they reach our ears.

Two main properties describe sound waves. Frequency, measured in hertz, sets the pitch, while amplitude sets the loudness, measured in decibels. Sound travels about 343 meters per second in air, much faster in water and faster still in steel.

Sound has countless uses. Echoes help bats and dolphins hunt, ultrasound lets doctors see inside the body and sonar maps the seafloor. Musicians, engineers and architects study acoustics to design instruments, concert halls and quieter cities.
