The following link is a great resource for understanding refraction and reflection 

http://www.myschoolhouse.com/courses/O/1/36.asp

 

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
