Waves
The transfer of energy.
What is a wave?
A reflected sound wave.
What is an echo?
The ability of a material to bounce back.
What is elasticity?
The part of the ear that connects the outer ear to the ear drum.
What is the ear canal?
The unit of measurement of the loudness of sound.
What is a decibel?
The beginning of a sound wave.
What is a vibration?
The bending of sound waves through an opening or around a barrier.
What is diffraction?
The amount of mass in a given space or volume.
What is density?
The lowest frequency we can hear.
What is 20 HZ?
This depends on the frequency of a wave.
What is pitch?
A wave where the medium moves parallel to the direction of the wave.
What is a longitudinal wave?
The bending of a wave as it enters a new medium.
What is refraction?
Sound frequencies above the normal human range.
What is ultrasound?
The level that hearing gets damaged.
What is 100 Db?
This depends on the amplitude of a wave.
What is loudness?
A wave where the medium moves at a right angle to the direction of the wave.
What is a transverse wave?
The noise generated by the pressure of an object traveling faster than sound.
What is a sonic boom?
Speed travels fastest in this medium.
What is a solid?
The part of the ear that transmits signal to the brain.
What is the cochlea?
The vocal cords or voice box.

Wavelength X Frequency
What is wave speed?
The apparent change in frequency in a wave as the source approaches an observer.
What is the Doppler Effect?
The reason Chuck Yeager broke the sound barrier at a high altitude.
What is sound travels slower because it is cold and the atmosphere is less dense?
The small bones of the middle ear.
What are the hammer, anvil, and stirrup?
The amount of energy a sound wave carries per second through a unit area.
