Have you ever wanted to learn how light works?
This series of lessons produced by Mr. Donaldson's Optics class at Montgomery Blair High School is designed to teach you how light behaves in many different situations.
If you are new to the material, it would be best for you to read through each lesson sequentially. But the lessons are also designed to be read separately, as reference.
Learn about Snell's law and how light moves between different media.
A proof that light rays horizontal to a parabolic mirror's axis reflect through the focus.
Explore the reflection of light off of mirrors and learn the mathematical basis for how the shape of a mirror affects reflected images.
Learn how to trace rays of light through convergent and divergent thin lenses.
When light enters prism and lenses, it refracts and reflects. Using Snell's law and geometry, learn to trace light through these objects!
This introductory lesson will teach you that...
Learn about how interference and partial reflection combine to give soap bubbles their unique optical properties.
Learn how modern physicists think about light and its interactions with electrons in metal.
Learn about the history of photography, starting with the camera obscura through modern film cameras.
