Electromagnetic Spectrum
This color of the visible spectrum has the highest energy.
Violet
Of solid, liquid, or gas, this is the state of matter through which sound travels the fastest.
Solid
The bending of light rays as they pass from one transparent medium to another.
Refraction
What is the distance between 2 corresponding parts of a wave called?
Wavelength
This is the part of the outer ear that vibrates in response to sound waves.
Ear Drum
This type of wave is used in medical imaging to view dense materials like bones.
X-Rays
Sound waves are produced by this physical action.
Vibration
This occurs when a wave bounces off a surface and changes direction.
Reflection
Unlike sound waves, EM waves do not require this, allowing them to travel through a vacuum.
Medium
The part of the ear that funnels sound waves into the ear canal.
Pinna
This type of wave is used to transmit cellular phone messages.
Radio Waves
Sound travels through a medium as what kind of wave?
Longitudinal
What does the law of reflection state?
The angle of incidence = the angle of reflection
What is the number of waves that pass a given point in a given amount of time?
Frequency
The nerve that carries sound messages to the brain.
Auditory Nerve
As you move from gamma rays to radio waves on the spectrum, this property decreases.
Frequency (Energy)
What is a reflected sound wave called?
Echo
This is the change in direction of a wave when it finds an obstacle or an edge, such as an opening.
Diffraction
Electromagnetic waves are described as these, meaning they oscillate perpendicular to their direction of travel.
Transverse Waves
The three tiny bones in the middle ear that amplify sound.
Hammer, Anvil, Stirrup
Electromagnetic waves travel at this specific speed in a vacuum.
300,000 km/s
(300,000,000 m/s)
The unit used to measure the intensity or loudness of sound.
Decibels
In a standing wave, these are the points that appear to have no motion, or zero amplitude.
Node(s)
What is the unit of measurement of frequency?
Hertz (hz)
This structure in the inner ear is filled with fluid and converts sound vibrations into neural signals.
Cochlea
