Light is a form of energy that enables us to see the world around us. We can see objects because they either emit light or reflect light that falls on them. This chapter explores how light behaves when it encounters different surfaces and materials. We study two fundamental phenomena: reflection, wh
Key Concepts
Two fundamental laws govern reflection
Two fundamental laws govern reflection: (1) The angle of incidence equals the angle of reflection, and (2) The incident ray, reflected ray, and normal
Spherical mirrors have curved reflecting surfaces
Spherical mirrors have curved reflecting surfaces that form part of a sphere. Concave mirrors curve inward (like a spoon's inner surface) and can form
The mirror formula 1/f = 1/v
The mirror formula 1/f = 1/v + 1/u relates focal length (f), image distance (v), and object distance (u). This formula works for all spherical mirrors
Refraction occurs when light passes from
Refraction occurs when light passes from one medium to another. The laws state: (1) The incident ray, refracted ray, and normal lie in the same plane,
The refractive index (n) of
The refractive index (n) of a medium is the ratio of the speed of light in vacuum to the speed of light in that medium: n = c/v. It indicates how much
