Matter can be understood by applying two scientific models: particles, and waves

Particle Models
Particles are objects that are hard, have mass, and move according to Newtonian mechanics.
Particles are a macroscopsic model which can be applied to the microscopic world.
Kinetic model of a gas: gas molecules are small, hard particles bouncing off of one another and the walls of their container. Macroscopic phenomena of pressure and volume are explained in terms of masses and speeds of the microscopic particles.
Particles show reflection and refraction.

Wave Models
Waves are shaped like a sine graph, but in practice waves are never shaped exactly like these.
Complicated waves can consist of much simpler waves.
Waves are a way in which energy is transferred from one place to another.
In a wave, something is changing in a regular way while energy is travelling/transferred along.
In water waves particles of water move up and down while energy is transferred horizontally.
Waves show reflection, refraction, diffraction, and interference but the last two are the defining characteristics of waves. If diffraction and interference are observed, waves are involved.
Waves do not have mass or charge.

Photons
All electromagnetic radiation consists of photons.
A photon is a packet of energy, or a quantum of electromagnetic energy.
Gamma-photons are the most energetic out of all the types of photons.
The energy of a photon is directly proportional to the frequency of the electromagnetic radiation of which it is a part of, so high frequency radiation means high energy

    Ocean waves are caused by many different factors. Usually waves are created by the wind; the wind transfers its energy to the water, through friction between the air molecules and the water molecules. The stronger the winds, the stronger the waves. Water waves usually do not go horizontally, they only move up and down. Some factors that also cause waves are tsunamis, earthquakes, and hurricanes. Surprisingly, wind speeds, the distance over which the winds blow, and the time that the winds are in contact with the water all determine the height and speed of the wave. Waves can travel thousands of miles from their source of “origin”. But it’s not the water moving, it’s the energy. As a wave approaches shore, friction between the bottom of the wave and the…

    Generally, ocean waves are created by “random pressure fluctuations in the turbulent wind … [and] reinforced in a feedback process that involves the airflow over the wavy surface” that creates a wave’s crests and troughs which travel at the wave’s phase speed (Garrett & Gemmrich 62). In other words, waves are created when the wind produces a ripple across the surface of a body of water that increases with the wind’s intensity and speed. Waves can also interact with currents, seabeds, and coastal features of shallow waters (Wallace par. 6).…

    Across from me was a handsome, dark haired man, broad-shouldered holding a Les Paul classic custom guitar playing melodious songs while I lay on a nice big red beach chair. In my hand was a big glass of iced tea shimmering in the bright sun as I took a sip it cooled the inside of my throat causing me to keep my cool temperature in the hot summer. It was the perfect day to be out, with the sun casting just the right amount of shine to give me that perfect sun-kissed tan. I was lying on a beautiful red chair with my legs sprung up in a gorgeous white cotton maxi dress. As, I got up and started to walk towards the ocean I could hear the waves up ahead. I took my shoes off and set foot on the hot, white sand. I could feel the sand going through in between my toes from every step I took. As I stroll along the edge of the beach I feel free of worries and stress, I am just enjoying the holidays, no school, or work just free time. In the middle of the ocean were many surfers in yellow shorts riding in the various color surfboards. They were going so fast doing so many tricks…
