Light pushes the shadow away from the object to the wall or the ground and is thought of as a "dark " reflection of the object. Light is not necessarily conserved. It may disappear or be intensified. Light from a bulb only extends outward a certain distance, and then stops.
Total Internal Reflection. An interesting case of refraction can occur when light travels from a medium of larger to smaller index. The light ray can actually bend so much that it never goes beyond the boundary between the two media. This case of refraction is called total internal reflection.
Based on your objectives for the group project, create a set of prompts using the questions below. Have students then use these prompts to journal about their reactions to group climate and process. The journals encourage self-reflection and can help students see teamwork issues in new ways and create ideas for resolution.
