    Study Notes

    Energy Forms

    • Light is a form of energy characterized as brightness from an object.
    • Heat is also a form of energy originating from a hot object.

    Importance of Heat and Light Energy

    • Heat and light energy are essential in daily life, making it almost impossible to live without them.
    • These two types of energy often occur together, with sources producing heat also producing light.

    Sources of Heat and Light Energy

    • The sun is the primary source of heat and light energy.
    • Other sources of light energy include light bulbs and fire.

    How Light Energy Works

    • Light energy helps us see objects around us by bouncing off them and traveling to our eyes.
    • Our eyes then send messages to our brain, enabling us to perceive what we're seeing.

    Luminous and Non-Luminous Objects

    • Luminous objects, such as the Sun or a light bulb, produce their own light.
    • Non-luminous objects, like the moon or toys, reflect light from other sources, making them visible to us.
