A beam of light can be bounced (reflected) off a smooth surface. If the object is transparent, the light passing through it is bent (refracted). 

When will the light be reflected? 

When will the light be refracted? 

How does the angle affect the light beam?

 

Refraction occurs to light when it travels from one substance/material to another. For example a pencil appears to bend when put in water; this is caused by refraction of light. The refraction occurs due to light waves traveling at different speeds in different substances/materials.

Reflection occurs when light is bounced back from a surface.Teh reflected beam will be bounced so the angle of reflection is equal to the angle of incidence, forming an image. With a flat mirror the image will be reversed from left to right.

If light is reflected off a rough surface then the reflected light is scattered and no image if formed.

 

How we see things:

·        That light travels from a source

·        To use their knowledge about light to make observations

·        That light from an object can be reflected by a mirror, the reflected light enters our eyes and we see the object

·        That when a beam of light is reflected from a surface, its direction changes

To make careful observations and comparisons
