Waves
These are a disturbance that transmits energy from one place to another.
What are waves?
This occurs when a wave bounces off a surface that doesn’t completely absorb its energy.
What is reflection?
As a starting point, this can be defined as the form of energy detectable by our ears.
What are sound waves?
This is a flap of cartilage that covers the trachea when you swallow to prevent food and drink from entering the lungs.
What is the epiglottis?
This is the only U.S. state that starts with the letter "P."
What is Pennsylvania?
The distance between crest to crest or trough to trough of 2 consecutive waves.
What is the wavelength?
This occurs when light travels from one medium to another.
What is refraction?
In order for sound to be transmitted it must have this.
What is a medium?
These are two flat pieces of mucous membrane tissue stretching across the upper portion of the larynx.
What are the vocal cords?
These are the three primary colors.
What is red, blue, and yellow?
This is produced by multiplying frequency x wavelength.
What is wave speed?
This occurs when a wave moves past a corner in its medium, it naturally folds or flows around the corner.
What is diffraction?
The speed of sound travels slowest in this.
What is gas?
This is also known as the "Adam's apple."
This is the tallest dog breed in the world.
What is a Great Dane?
A wave that moves across a medium in a direction perpendicular (vertically) to the direction in which the wave travels.
What is a transverse wave?
As the source of waves or the observer move toward each other = frequency is higher. As the sources of waves or the observer moves away from each other - frequency is lower.
What is the Doppler Effect?
What is pitch?
This is the snail-shaped tube in which sound is converted into nerve impulses.
What is the cochlea?
This country produces the most coffee in the world.
What is Brazil?
A wave that moves across a medium in a direction parallel (horizontally) to the direction in which the wave travels.
What is a longitudinal wave?
The matter through which mechanical waves travel.
What is the medium?
The particular sound of an instrument is known as this.
What is quality?
This helps to equalize the air pressure on both sides of the eardrum.
What is the eustachian tube?
This animal does not have a larynx.
What is a giraffe?
