The following link is a great resource for understanding refraction and reflection
We have also covered transparent, translucent, and opaque objects.
Transparent: ALL light passes through an object.
Translucent: SOME light passes through an object.
Opaque: NO light passes through an object.
Here are the vocabulary words we will be focusing on during the light unit.
Wavelength - the distance from the top of one wave to the top of another
Transparent - letting all or nearly all light pass through
Opaque - blocking all or most light from passing through an object
Reflection - the bouncing of light or sound waves off a surface
Prism - an object, usually made of glass, that bends light. It seperates white light into bands of colored light
Electromagnetic Spectrum - the range of wavelengths that make up light
Refraction - the bending of light as it passes from one material into another
Translucent - letting only some light through
