✋Introduction
Refracting light
In this lesson: I can describe and draw how a ray of light refracts when it moves from one medium to another, and explain how refraction can cause virtual images. Light changes direction when it moves into a new medium (material) at an angle to the normal. This is called refraction. When light enters a transparent material from air, it turns towards the normal.
Lesson outcome
Waxaan sharxi karaa oo sawiri karaa sida iftiin uu u qallooco marka uu ka gudbo hal dhexdhexaad (medium) una gudbo mid kale, waxaana sharxi karaa sida qallooca uu u keeni karo sawirro aan dhab ahayn (virtual images).
