ECHO
An echo is produced when the sound reflected by an obstacle situated at a certain distance reaches the ear in such a way that both the initial sound ad the reflected sound can be distinguished.
REVERBERATION
When a sound is reflected at a distance of less than 17 m from where we are.
EYE
Sclera-Cornea-Iris-Pupil-Lens-Retina-Optic Nerve
HOW DOES THE EYE WORK?
Light enters the eye through the pupil
The lens focuses the image
The retina receives the image and transforms it into nerve signals
The optic nerve transmits the information to the brain
Our vision is binocular
EAR
Outer Ear:Pinna
Middle Ear:External auditory canal-Eardrum
Inner Ear:Hammer-Anvil-Stirrup-Ossicles-Semicircular Canals-Cochlea
HOW DOES THE EAR WORK?
The pinna captures the sounds and the outer ear canal transmits them to the interior of the ear
The eardrum vibrates when it receives the sounds
The bones of the inner ear transmit the vibration to the ossicles
There are sensitive cells in the ossicles
HEAT
Is a form of energy which can be transformed and transmited.
transfomed to kinetic energy or luminous energy.
TEMPERATURE
Is a physical magnitude that is related to the amount of heat that can be released or absorbed by body.
Solids which transmit heat well.Are conductors.And badly.Insulators
