Waves
Waves carry what
Energy
radio waves Have the longest wavelengths and the lowest _______
Frequency
allows for the passage of light into the eye and it also focuses the light
Cornea
What are the 3 Main Components of the Hearing Mechanism
Outer Ear
Middle Ear
Inner Ear
A lens that curves outwards is called a
Convex lens
material through which a wave transfers energy
medium
When light enters a new medium it bends (refracts). Each wavelength bends a different amount allowing white light to separate into
ROYGBIV
controls the amount of light entering the eye
Iris
Collects sound and Helps in sound localization
Pinna/outer ear
A lens that curves inwards is called a concave lens.
Concave Lenses
Waves that don’t need a medium
electromagnetic wave
Used to kill bacteria.
UV
supports eyeball and provides attachment for muscles
Sclera
Provides support to the external ear and posterior wall of the middle ear cavity
Mastoid
The light that enters the eye is refracted by the __________
cornea
Waves are caused by what
Vibrations
The sun Causes your skin to produce what
Vitamin D
Brain takes inverted image and flips it so we can see
OPTIC NERVE
What are the 3 Ossicular bones
Malleus
Incus
Stapes
In a concave lens light rays spread _________
parallel
medium vibrates ________ to the direction of wave motion
perpendicular
______ waves use thermogram
INFRARED
On retina where optic nerve leads back into the brain
Blind spot
What is a Cochlea
Snail-shaped organ with a series of fluid- filled tunnels; converts mechanical energy into electrical energy
The focal length of a converging lens depends on two factors
The shape of the lens
The index of refraction of the lens material
