Transmission: Light passes through an object and continues travelling. Example: Clear glass. Absorption: Light is absorbed by (remains in) the object and turned into heat. Reflection: Light bounces off the object and travels in another direction.
ACTIVITY 4.3: Page 292 of textbook Exploring the Properties of Light In groups of 3. Amongst your group members, decide who will be the MATERIAL manager, the TASK manager, and the SAFETY officer.
