Science Summary:
Measuring waves:
Amplitude
An amplitude is a measurement of how far a wave rises or falls from its starting point. As a result, a high amplitude wave will carry more energy than a low amplitude wave
Wave length
The wavelength of a wave is a measurement of the distance from the peak of one wave to the other peak.
Time period
The frequency of a wave is also related to the time period of a wave. The time period is now long it takes each wave to pass a point.
Frequency
Frequency is a measurement of how many full oscillations occur in a second or how long it take to full oscillation to occur

Sensitive to energy:
-
The pupil is surrounded by the iris, which is the colored part of our eyes
Light is further directed by another lens. This lens can be stretched by the ciliary muscle so that it can focus light rays onto the retina.
The greatest destiny of these cells is around a small depression in the retina called the fovea, which contains the cells that allow us to see color
Waves meeting:
When waves meet a barrier, they may be able to pass through or they may bounce back.
EG: Light waves can pass through the glass in a window, but sound waves will most likely bounce back.
-
Wave cannot move matter:
Even though waves involve movements, they cannot move matter. Any motion of material that a wave travels will result in the matter returning to its original position.
EG: A small insect, crawling on a rope and when the waves pass, it would be thrown up by the passing wave.
Measuring sounds:
A sound wave with a large amplitude carry more energy and sounds louder. A quiet sound has a smaller amplitude.
Sounds with high frequency and short wavelength will sound higher in pitch while low frequency sounds lover in pitch
What are waves?
Waves are a disturbance that contains energy from a location to another. This movement is known at Propagation
Transferring energy:
When the ocean waves pass, they cause the joints between the different sections to bend. This action is used to convert transferred energy of the waves into electrical energy
Travel on water:
The water level goes up and down, and the disturbance travels with the surface of the water.
