PPT-REFRACTION

When light travels from one material to another it usually changes direction The bending of light that occurs at the borderline of two materials is called refraction Geometrical concepts incident ray. RAY OPTICS -I Refraction of Light: Refraction is the phenomenon of change in the path of light as it travels from one medium to another (when the ray of light is incident obliquely). It can also be de pp. 562 -567. Mr. Richter. Agenda. Warm-Up. Introduction to Refraction Demo. Reminder: Quarter 3 Ends Friday. Notes:. Refraction. Index of Refraction. Why Light Bends.

From the last chapter, we know how light behaves when it travels in space or in the air – i.e. it travels in a straight line.. When light strikes a plane mirror, the angle of incidence = the angle of reflection. . Intro to Refraction. Take 3 cups from the front, labeled 1,2,3. .

Refraction of light occurs when a light wave moves from a vacuum (or a medium) into another medium (or a vacuum). When a wave changes media, its ____________ changes..
