Name the type of wave that travels through the Earth.
Seismic Waves
Tsunamis
Waves caused by earthquakes or undersea volcanic eruptions: giant waves
Pupil
Allows LIGHT into the Eye
What are Longitudinal Waves?
Sound Waves
What holds photoreceptors known as RODS & Cones?
Retina
Describe a Seismic "P-Wave"
Short primary waves; travel the fastest
Coastal Waves
POTENTIAL ENERGY transported across 100's to 1,000's of miles of ocean to be released as KINETIC ENERGY when they break on the coast.
Light Duality
Light is both PARTICLES and WAVES.
Particles behave in wave form.
What travels through a medium but cannot travel through a vacuum, like Outer Space
Sound Waves
What CONTROLS the amount of light allowed into the eye?
Iris
From the midpoint of a wave (rest) to the top of a wave.
The height or vertical height of a wave
Amplitude
Tides
Rising and falling of the sea
Twice in each lunar day at a particular place
Caused by moon and sun GRAVITY PULL
the number of waves that pass a fixed point in a given amount of time.
FREQUENCY
Cochlea
Function of Schlera
1. Protection
2. Shape
Short, secondary waves that move slowly and arrive later than S-WAVES.
S-WAVES.
Wavelength
Distance from top of one wave to the next wave.
=wavelength
=velocity
=frequency
Electromagnetic Spectrum
The RANGE of frequencies of electromagnetic radiation and their wavelengths and photon energies.
A lens with 2 indents on the side to help refract light waves outwards
CONCAVE
The ________ acts as the eye's outermost lens. It functions like a window that controls and focuses the entry of light into the eye. The cornea contributes between 65- 75 % of the eye's total focusing power
CORNEA
The density, of a substance is its mass per unit volume.
d=mass/volume
The density
Ocean Currents are formed by:
Salinity, density and temperature changes in the water
A PARTICLE representing a QUANTUM of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.
PHOTONS
Lens found in our eyeballs; oval shaped lens that BENDS rays/waves to FOCUS image on the RETINA
CONVEX
Schlera
Tough, white part of the eye
