### 1. Mirrors: Difference Between Plane & Spherical

A mirror surface can produce clear reflections due to its smooth surface. Explore the difference between the two types of mirrors, plane and spherical, and the problem with aberration that is solved using parabolic mirrors.

### 2. Ray Tracing with Mirrors: Reflected Images

Ray tracing is a simple way to draw what would otherwise be dozens and dozens of photons of light to illustrate reflected images. Learn about the law of reflection and how to draw a ray tracing diagram with a mirror using an example.

### 3. Using Equations to Answer Mirror Questions

Equations can be used to answer mirror questions in order to predict what an image will look like. Learn the basics of mathematically calculating mirror images, including using lens equations, then practice what you learned with example calculations.

### 4. Thin Lens Equation: Examples & Questions

The thin lens equation is used to make predictions on what a lens will do. Explore the types of lenses and how to use the thin lens equation, with example calculations and questions.

### 5. Using Equations to Answer Lens Questions

Lens equations are those that calculate the imagery observed through a lens. Learn how these equations function, calculate answers to questions about the images that a given lens will produce regarding size, inversion, and clarity.

### 6. Polarization of Light & Malus's Law

Polarization is essentially filtering out the chaotic light-wave oscillations to achieve a more clear, and 'polar' experience of light. Explore how glasses, screens, and radios polarize, and understand Malus's law, which calculates the way to dim light to polarize effectively.

### 7. Polarization by Reflection & Brewster's Law

Polarization by reflection occurs as light bounces off a reflective surface, and is polarized in the process. Identify the reason for this through examples, and see how Brewster's law explains why the angle of refracted rays can calculate the polarization.

### 8. Diffraction & Huygen's Principle

Diffraction is the spreading of a wave when encountering an obstacle, or a slit. Discover different types of diffraction in real-life examples, and explore Huygen's principle that explains the observed behavior of waves and wavelets.

### 9. Single-slit Diffraction: Interference Pattern & Equations

Single-slit diffraction occurs when light spreads out when passing through or around an object if one color light is used and a relatively thin slit is used. See the pattern in this diffraction and learn the equation that explains the observations made.

### 10. Double-slit Diffraction: Interference Pattern & Equations

A double-slit diffraction is the observed effect where light passing through two slits creates beams that interact with each other. Explore the interference pattern and equations that explain the observed phenomena with light passing through double-slits.

### 11. Multiple-slit Diffraction: Interference Pattern & Equations

A diffraction grating is a grid of slits scratched into glass in a crisscross pattern and has many different uses, from medical imaging to genetic research and fiber optics. Learn more about different uses of diffraction gratings and how to use the equation for calculating the maxima through real-world examples.

### 12. How Thin Film Interference Works

Thin film interference is an observed pattern of distortion that occurs as thin layers of substances are stacked onto of each other. Learn how this is caused similar to sing/double-slit refraction, and the equation used in an example problem demonstrating constructive, and destructive film interference.

### 13. Michelson Interferometer: Applications

A Michelson interferometer is a device that splits a beam of light in two and then recombines them into one. Learn more about the Michelson interferometer's characteristics, history, purposes, and applications.
