Can we perceive(see) frequency differences in waves without specifically measuring them?
What is frequency a measure of:
Frequency is a measure of how many wave crests pass a point in a certain amount of time.
For sound waves, a greater frequency is perceived as
a lower pitch
a higher pitch
louder sound
softer sound

different brightness levels
different colors
different shapes
different intensities
Water waves will appear closer together if you stand on the shore and watch them when their frequency is higher
Why do sound waves travel fastest through solids than through liquid and gases.
Because the molecules in gases are more energetic and vibrate more
Because the molecules in solids are closer together, requiring less energy to transfer
Because gases are less dense, allowing vibrations to pass through more easily
Because solid absorb more energy, which propels the sound wave forward
Imagine sound traveling though three different mediums steel(solid), pool(liquid), and air(gas) in a room. Which medium would sound travel the farthest and fastest.
steel
water
air
What property of matter most influences how fast sound waves travel through it?

What is the difference between a sound and a sound wave?
Sound is the perception of vibrations; a sound wave is the physical wave that carries those vibrations.
