Wave Properties
Waves carry this from one place to another.
What is energy?
The classification of sound because it requires a medium to travel through.
What is mechanical?
Classification of light because it can travel in a vacuum.
What is electromagnetic?
The only electromagnetic wave that can be detected by the human eye.
What is visible light?
Sound is a ___________. The ear turns these ____________ into nerve signals for the brain.
What are vibrations?
What is the amplitude?
The medium that sound travels the fastest in.
What are solids?
300,000,000 meters per second.
What is the speed of light?
Because an objects reflects or emits light.
How do we see something?
Part of the ear that captures sound waves and directs them inwards.
What is the outer ear?
This distance between two consecutive wave.
What is the wavelength?
This characteristic of sound is altered when the frequency or wavelength is changed.
What is the pitch?
Form of light that is invisible to the human eye but can cause sunburn.
What is ultraviolet?
Part of the eye that responds to the amount of light in the room.
What is the pupil?
Part of the ear that turns the vibrations from the ear drum and ossicles into nerve signals?
What is the inner ear?
Measures the rate of vibration in hertz.
What is frequency?
This characteristic of sound is altered when the amplitude is changed.
What is volume or loudness?
The property of a light wave that determines the color of light.
What is the wavelength/ frequency.
Wavelengths of color that are reflected off a white surface.
What are all the wavelengths of color?
Name for the three small bones in the ear.
What are the ossicles?
The point on a longitudinal wave where molecules are expanded.
What is rarefaction?
Method of using reflected sound to locate objects that is used by some animals.
What is echolocation?
The property of a light wave that determines the brightness.
What is the amplitude?
Special nerve cells found in the retina for detecting color.
What are cone cells?
Other purpose of the ear besides detecting sounds.
What is balance?
