Study Notes
Light and Energy
- Light carries energy, which is transferred to objects in the form of heat.
- Evidence of this energy transfer can be seen when an object left under the sun gets hot.
Properties of Light
- Light is composed of tiny particles that move in waves.
- These particles travel in straight lines, known as rays of light.
Interaction with Objects
- When light hits an object, it either penetrates the object or bounces off it.
- The bouncing of light off an object is called reflection.
Importance of Reflection
- Reflection of light enables us to see things.
- It is an essential aspect of our ability to perceive the world around us.
Propagation of Light
- Propagation refers to the travel of light from a source to a different location.
- Natural sources of light include stars and fire.
- Modern sources of light include electric lights in homes, vehicles, and streetlights.
Reflectors vs. Sources of Light
- Some objects, such as the moon, do not produce light but rather reflect light from other sources.
- Other objects, like reflective jackets and mirrors, are designed to effectively reflect light.
