Electromagnetic Waves detected by the eye
Light
What is the difference between cone and rod cells in the retina
The cone cells allow you to see colors like red, blue and green. While the rod cells allow you to see blacks grays and shadows
The first part of the middle ear
The ear drum

If a speaker has a low volume and you wanted to draw the sound wave it would have a _____ _______
Low amplitude
Absorption is
When light is taken in by an object
Which two types of waves need a medium to travel
Sound waves and water waves
The part of the outer ear that you can see
The Pinna
An opening of the eye that lets light in, it can be a black dot
The Pupil
If a wave has a lot of energy then the wave also has a _______ _________
Long wavelength
When light bounces off and object and changes direction
Reflection
Why would a ball floating in the ocean bounce up and down, but not move side to side like waves
Because waves do not carry matter they only transfer energy
3 bones inside the middle ear
The ossicles
The part of the eye that stretches or shrinks to focus on things close and far away
The Lens
Someone with a high squeaky voice their sound wave would have ___________ and ___________.
A high frequency and short wavelength
When light bends as it passes from one medium to another
Refraction
What is the process of bats using echolocation to find their prey?
Bats make a low pitch sound in their throat, then send the sound into the air and listen to the echos of the sound bounce off the surroundings. Then they send a high pitch sound to listen for the small flies and bugs
The Part of the Inner ear that transfers sound waves to the brain
The cochlea
The part of the eye that sends neurons and light waves to the brain
The Optic Nerve
Sound waves need a __________ like solids, liquids and gases to travel
Medium
What is the process for an animal receiving, processing, and responding to a light wave?
First there has to be light reflected into the eye, then the light waves travels to the brain, then the brain processes the information and responds
Explain the process of seeing an apple
First the sun or a light source has to hit the apple, then the light waves are processed by traveling from the cornea, to the iris, to the pupil, to the lens, to the retina, to the optic nerve, changes into signals that are sent to the brain
