Study Notes
- We are going to review a light in the next 30 minutes, and will examine all its concepts in detail. starting with the basics.
- Light is a form of energy that reduces the sensation of objects by producing light sessions, enabling us to see their shop sizes, colors, etc.
- Light has some key properties, such as propagation through three-time media - 10 meters per second in a vacuum, but can vary in other media.
- Light always travels in a straight line, as per rectilinear propagation, and is essential for reflection and refraction.
- Reflection is the process by which a light bounces back from a smooth surface, creating a reflected wave, such as a mirror reflecting light and the amount of reflection being directly related to the angle of incidence.
- The incident and reflected rays make equal angles with the normal or the reflecting surface.
- There are some losses in the reflection, especially when the angle of incidence is very small, such as English angles, where the incident and reflected angles are both small, causing significant energy loss.
- The first loss in the reflection is English of insides, where the incident and reflected angles are both small, and the second loss is called reflected refracted rays or refracted normals, which also affect the behavior of the light in different media.
- Some other losses occur in the reflection, such as absorption and scattering, affecting the quality and intensity of the light.
- The reflection, refraction, and transmission properties of light are essential in various fields, including optics, photography, and material science.
