Light Reflection and Related Phenomena

The video tutorial introduces the concept of reflection in physics, explaining how light bounces back when it hits a surface, similar to a ball bouncing off a wall. It defines reflection as the bouncing back of light and describes the roles of incident and reflected rays, along with their respective angles. The tutorial outlines the laws of reflection, stating that the incident ray, reflected ray, and normal lie on the same plane, and that the angle of incidence equals the angle of reflection. It differentiates between regular and irregular reflections and introduces the concept of lateral inversion, where an image appears reversed in a mirror.

What is the phenomenon called when light bounces back after hitting a surface?

• Reflection

• Absorption

• Diffusion

• Refraction

What is the main reason we can see objects around us?
