Light is a vital form of energy that allows perception of objects through its travel in straight lines at a speed of 3 × 10^8 m/s. Its characteristics include reflection, refraction, and dispersion, and it demonstrates both wave-like and particle-like properties. Understanding the laws and types of reflection, as well as the behavior of plane mirrors, enables practical applications in various optical instruments.

Light is essential for vision and travels in straight lines.
Reflection occurs when light bounces off surfaces, following specific laws.
Plane mirrors create virtual images with unique characteristics.
The principle that light travels in straight lines.
The incident ray, reflected ray, and normal lie in the same plane; the angle of incidence equals the angle of reflection.
