The section labeled λ represents:
What is Wavelength?
100
The difference between these 2 waves is their: 
What is Frequency?
100
The job of the tiny hairs in our ear.
What is converting sound waves into electrical signals our brain can understand?
100
Humans have evolved to not ignore this type of sound.
What is a baby crying?
100
The reason amplitude of a sound wave decreases over time.
What is the energy is lost due to friction?
200
Line B represents:
What is Amplitude?
200
Light is this type of wave:
What is Transverse?
200
The structure in the ear that vibrates first when sound waves enter the ear canal.
What is the ear drum?
200
The unit that measures sounds humans can hear.
What is decibels (dB)?
200
This type of material is less likely to absorb sound waves.
What is a smooth, hard surface?
300
Point A & C are called:
What is A = Trough, C = Crest?
300
This color of light has the most energy, this color of light has the least:
What is Purple has the most, Red has the least energy?
300
The part of the ear that converts sound waves into electrical signals that the brain can interpret.
What is the cochlea?
300
The speed of this is 770 miles per hour.
What is sound?
300
This is when sound waves bounce off a surface, and you can hear them again.
What is reflection (echo)?
400
Which part of a wave tells you how much energy it has?
What is Amplitude?
400
Sound is this type of wave:
What is Longitudinal?
400
This structure amplifies sound waves as they travel through the middle ear.
What is the ossicles?
400
This common organism cannot hear at all.
What is a fly?
400
This process is called transmission.
What is a wave passing through transparent material without changing direction?
500
Changing the pitch of a sound will change this part of the sound wave.
What is the size of the wavelength?
500
A region in a longitudinal wave where the medium's particles are spread farthest apart, resulting in low pressure and density.
What is Rarefaction?
500
When you move your head, the fluid in these structures shifts, triggering a signal to the brain about the body's position, which helps maintain balance.
What are the inner hair cells (IHC)?
500
A whip creates this when it is snapped, the tip moves faster than the speed of sound, which creates the cracking noise.
What is a mini sonic boom?
500
This process is when sound changes direction when it moves from one substance to another, such as from air into water, because the speed of sound is different in each.
What is refraction?
