Which two properties of a sound wave change when the pitch gets higher?
Which two properties of a sound wave change when the sound gets louder
What are two factors that affect the speed of sound?
Sound waves make the eardrum vibrate.
Vibrations pass through three small bones – hammer, anvil, and stirrup.
Stirrup sends waves to cochlea and basilar membrane. Hairs near the membrane send an impulse through nerves to the brain.
To create sonograms, why are ultrasound waves used instead of audible sound waves?
How is reflection from objects that appear blue different than reflection from objects that appear yellow?
Describe how a mirage is formed.
If light traveled at the same speed in raindrops as it does in air, could rainbows exist? Explain your reasoning.
