Light Waves
A disturbance that moves energy from one place to another
What is a wave?
In this wave, particles move along with the path of the wave(left to right)
What are Longitudinal Waves?
The round, dark, center of the eye that opens and closes to regulate the amount of light that enters the eye
What is the Pupil?
The outer part of the ear
What is the Pinna?
Waves in which particles vibrate in an up and down motion (moving across); particles in the medium move perpendicular to the direction of the wave
What are Tranverse Waves?
A section of a longitudinal wave where particles are crowded together
What is Compression?
The part of the eye that focuses light rays on the retina is called
What are the lens?
How does sound travel?
An object vibrates and those vibrations travel in all directions as longitudinal waves
The highest peak of a transverse wave
What is Crest?
A section of a longitudinal wave where particles are less crowded than normal
What is Rarefaction?
Connects the eye to the brain
What is the Optic Nerve?
This membrane separates the inner ear from the outer ear
What is Ear Drum?
Measure of the distance between the waves
What is Wavelength?
Sound waves travel fastest through these
What are Solids?
Colored part of your eye
What is the Iris?
This part of the ear contains tiny hairs that help translate sound vibrations into electrical signals sent to the brain
What is the Cochlea?
The distance from the center point of the wave to the crest; measures amount of energy in a sound wave
What is Amplitude?
Light is bent as it passes from the air into the lens of eyeglasses. The bending is called
What is Refraction?
True or False: Humans see images upright the first time
False
The main purpose of the outer ear , middle ear and inner ear
What are collect, transmit and translate sound?
