Introduction
Optics is the branch of physics which involves the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it.
Pre-Requisites:

Activity:
Refraction of light through water.
Real Life Question:
What is Refraction?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Refraction | Refraction is a phenomenon that often occurs when waves travel from a medium with a given refractive index to a medium with another at an oblique angle. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Prism | The degree of bending of the light's path depends on the angle that the incident beam of light makes with the surface, and on the ratio between the refractive indices of the two media. |

What you learn in Theory:
Refraction is a phenomenon that often occurs when waves travel from a medium with a given refractive index to a medium with another at an oblique angle.
What you learn in Practice:
Refraction can make objects appear closer than they are; it is responsible for allowing water to magnify objects.
