This investigation requires children to use mirrors accurately and think about light and reflection first, you will need the pdf resource below can the children explain what is happening to the number of reflections as the angle of the mirrors is reduced can they explain why this happens. A selection of images and text covering reflection - mirrors, reflection - seeing objects, light sources and light rays reflection interactive when we see things, light travels in a straight line from a source to an object, and then bounces (or reflects) into our eye. Give a light source the raspberry and watch it wiggle—but the only thing wiggling is you.
Specular reflection creates a mirror effect—not only direct light is reflected perfectly, the same happens to the indirect rays (moving from the light just look around, keeping in mind all you see is light locate the specular and diffuse reflection, observe shadows and create your own rules for it. Light, shadows and reflection the objects that give out or emit light of their own are called luminous objects example: sun a shadow is always dark and does not depend upon the colour of the object it is obtained only on a screen we need a source of light and an opaque object to see a shadow on. If rays are blocked by an opaque object a shadow forms where the light cannot reach if the light source is moved closer to the object, more light is blocked and a larger shadow is formed how does sunlight cause shadows.

Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated common examples include the reflection of light, sound and water waves.
Light behaves as a wave - it undergoes reflection, refraction, and diffraction just like any wave would yet there is still more reason to believe in the wavelike nature of light continue with lesson 1 to learn about more behaviors that could never be explained by a strictly particle-view of light.
