Light Bright
100
The type of wave that has compressions and rarefactions.
What is compressional wave?
100
This is the "sound collector" portion of the ear.
What is the outer ear?
100
This part of the eye is a thick, white, covering that protects the eye.
What is the sclera?
100
Sound travels fastest through this material.
What are solids?
100
This is the change in direction of light waves through a material such as water.
What is refraction?
200
The wave that causes particles to move back and forth at right angles to the direction in which it travels.
What is transverse?
200
This part of the ear controls balance.
What are the semicircular canals?
200
This part of the eye focuses light onto the retina.
What is the lens?
200
This is the human perception of frequency.
What is pitch?
200
Light waves are classified as this type of wave.
What is electromagnetic?
300
This is how you find the wavelength of a compressional wave.
What is the distance from compression to compression OR rarefaction to rarefaction?
300
This part of the ear amplifies sound waves and delivers the waves to the inner ear. (Must get all 3 correct to receive points!)
What are the malleus, incus, and stapes OR hammer, anvil, stirrup?
300
is the opening of the eye that allows light in. It can appear smaller when a light is shined on it.
What is the pupil?
300
This is the process of locating objects by bouncing sounds off them.
What is echolocation?
300
These cells in your eye help you see in dim light.
What are rods?
400
The number of wavelengths that pass by a point each second.
What is frequency?
400
This part of the ear converts sound waves into electrical impulses.
What is the cochlea?
400
This part of the eye contains rod and cone cells and receives images from the lens.
What is the retina?
400
This is the term for repeated echoes.
What is reverberation?
400
This portion of the electromagnetic spectrum can be detected by the human eye.
What is visible light?
500
Waves that can travel through matter or empty space.
What are electromagnetic waves?
500
This part of the ear vibrates when hit by sound waves.
What is the tympanic membrane OR eardrum?
500
This is the colored part of the eye that controls how much light enters the eye.
What is iris?
500
This is the unit of measure for sound intensity.
What are decibels?
500
Condition of the eye where a person can see up close, but has trouble seeing far away objects.
What is nearsightedness?
