 Here’s a summary of key concepts from Chapter 13, "Light," typically found in an 8th-grade science textbook: Chapter 13: Light 1. Nature of Light: Definition: Light is a form of energy that travels in space and can be perceived by the human eye. Dual Nature: Light exhibits both particle and wave characteristics. It behaves as a stream of particles called photons and as a wave. 2. Properties of Light: Rectilinear Propagation: Light travels in straight lines in a uniform medium. This is why shadows are sharp-edged. Reflection: When light bounces off a surface, it is reflected. The laws of reflection state that: The angle of incidence (angle between the incident ray and the normal) is equal to the angle of reflection (angle between the reflected ray and the normal). The incident ray, the reflected ray, and the normal lie in the same plane. Refraction: Light bends when it passes from one medium to another with a different density. This bending is due to a change in the spee...
