Electromagnetic radiation has properties of both waves and particles. It travels at the speed of light in a vacuum and its frequency or wavelength can be calculated using a specific equation. As EM radiation has a particle nature, the energy of individual photons can also be calculated using Planck's constant and the frequency, with higher frequencies corresponding to higher energies. The EM spectrum consists of different types of radiation ordered from lowest to highest energy: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, with gamma rays being the most energetic and penetrating.

It also covers finding the height of buildings and calculating angles of elevation and depression. More practice problems can be found on the listed website.
12 euclidean geometry
MNOP is a parallelogram because it has both pairs of opposite sides that are parallel and equal in length. We can use properties of quadrilaterals and geometry to prove shapes are specific types of quadrilaterals. For example, the diagram shows that S is the midpoint of MN, T is the midpoint of NR, so U must be the midpoint of NP. We can prove conjectures about lines and angles using properties we know.
Optical phenomena and properties of matter
The document discusses optical phenomena and properties of matter in physics. It describes the photoelectric effect where electrons are emitted from a substance when light shines on it. The number of emitted electrons increases with light intensity. It also discusses work function, which is the minimum energy needed to eject electrons from a metal. Emission and absorption spectra are formed when certain light frequencies are emitted or absorbed by gases and materials, respectively, due to electrons moving between energy levels.
Electrodynamics
There are two types of electrical generators - AC and DC generators. AC generators, also called alternators, convert mechanical energy into alternating electrical energy, while DC generators produce direct current. Electric motors operate by using a current in a loop of conductor to generate opposing Lorentz forces on opposite sides of the loop, causing the loop to rotate. Alternating current has a root mean square (RMS) value which is the maximum value divided by the square root of two and is used to calculate average power in a resistive circuit with AC.
Electric circuits - grade 12

Ohm's Law describes the relationship between current, potential difference, and resistance for circuit elements. The equivalent resistance of resistors can be calculated differently depending on whether they are connected in series or parallel. Real batteries have an internal resistance that affects their potential difference output.
Electrochemistry
This document discusses electrochemistry and provides definitions and examples of key concepts. It defines oxidation as the loss of electrons and reduction as the gain of electrons. An electrochemical reaction is one where a chemical reaction produces an electric current or where an electric current causes a chemical reaction. There are two types of electrochemical cells - galvanic cells where a chemical reaction produces a current, and electrolytic cells which use electricity to drive a non-spontaneous reaction. The document also discusses standard electrode potentials and how they are used to calculate cell emf and predict reaction spontaneity. Industrial applications of electrochemical cells mentioned include electrolysis, chloralkali production, and metal extraction from ores.
The chemical industry

It also mentions major chemical companies like Sasol. The document then explains that the fertilizer industry is important for providing nutrients to plants and crops. It describes how plants and animals need macronutrients and micronutrients to survive and how fertilizers provide these nutrients either organically from materials like manure or inorganically through industrial processes.
Doppler effect
The document discusses the Doppler effect, which is a change in observed frequency of a wave when the source or detector moves relative to the transmitting medium. The Doppler effect can be seen in all types of waves, including sound, light, and radio waves. Sonography uses ultrasound and the Doppler effect to determine the direction of blood flow. Light from stars also exhibits the Doppler effect, with stars appearing redder due to decreased frequency, indicating they are moving away from Earth - evidence that the Universe is expanding.
Acids and bases
The document discusses acids and bases according to different definitions. The Arrhenius definition defines acids as substances that increase the concentration of hydronium ions and bases as substances that increase the concentration of hydroxide ions in a solution. The Brønsted-Lowry definition is broader, defining acids as substances that donate protons and bases as substances that accept protons. Amphoteric substances can act as both acids and bases, while amphiprotic substances are acids and bases according to the Brønsted-Lowry definition. The document also discusses acid-base reactions, the pH scale, and titrations.
Chemical equilibrium
This document discusses chemical equilibrium, which occurs when the rate of the forward reaction equals the rate of the reverse reaction in a closed system. It defines the equilibrium constant (Kc) and explains that a high Kc value means a high product yield, while a low Kc means a low product yield. It also describes Le Chatelier's Principle, which states that applying stress to a system in equilibrium will cause the equilibrium to shift to reduce the effect of the stress, and discusses how temperature, concentration, and pressure influence the position and value of equilibrium constants.
Rate and extent of reaction
This document discusses reaction rates and factors that affect reaction rates. It explains that reaction rate is calculated based on the moles of product formed or reactants used over the reaction time. The rate of reaction is affected by properties of the reactants, concentration, surface area, pressure, temperature, and presence of a catalyst. Various methods can be used to measure reaction rates depending on the products, such as collecting gases, measuring precipitates, or observing color changes. For a reaction to occur, particles must collide with sufficient energy to overcome the activation energy, and increasing temperature or adding a catalyst can provide this energy. A catalyst lowers the activation energy and speeds up the reaction but remains unchanged after.
05 work-energy-and-power
This document discusses concepts related to work, energy, and power in physics. It defines kinetic energy and explains the conservation of energy and mechanical energy. Work is defined as the transfer of energy by a force acting along an object's path of motion. The work-energy theorem states that the work done on an object equals its change in kinetic energy. Power is the rate at which work is done or energy is transferred, with the mathematical definition being the work done divided by the time taken.
Vertical projectile motion
1. The document discusses vertical projectile motion, where objects move up and down under the influence of gravity.
2. Objects in vertical projectile motion experience a constant downward acceleration of 9.8 m/s^2 due to gravity. The time it takes an object to rise is equal to the time it takes to fall back to the initial height.
3. Equations of motion can be used to solve problems involving vertical projectile motion relating to displacement, velocity, acceleration, and time. Position-time and velocity-time graphs are similar to constant acceleration motion and depend on the initial velocity and position coordinates chosen.
Momentum and impulse
The document discusses momentum, impulse, and Newton's laws of motion. It defines momentum as the product of an object's mass and velocity, and explains that the net force acting on an object is equal to the rate of change of its momentum according to Newton's second law. It also describes the principle of conservation of momentum in isolated systems, and defines elastic and inelastic collisions. Finally, it states that impulse is equal to the change in an object's momentum, where impulse is defined as the product of net force and the time interval for which it acts.
Organic molecules
Organic chemistry deals with carbon-containing compounds called organic molecules. Carbon atoms can bond to many other atoms, often forming long chain structures. Organic compounds can be represented using molecular formulas or structural formulas. They contain functional groups that give them certain chemical properties and can be classified based on these groups. Organic reactions include addition, elimination, and substitution. Polymers are large molecules formed by combining repeating structural units (monomers) and include both natural and synthetic varieties.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
