What is the use of light?
Light is the sole source of food generation for all living organisms on the earth. Almost all living beings depend on light for their food and energy. Plants and other autotrophs synthesize their own food materials by use of light. The light which falls on the leaves of a plant is trapped.
What are the uses of light at home?
Lighting plays such an important role in a home. From setting mood to adding interest, lighting is central in creating perspective in a space. Uplights and downlights significantly add a layer to a room that may not have existed before.

How does the use of light affect living things?
Almost all living beings depend on light for their food and energy. Plants and other autotrophs synthesize their own food materials by use of light. The light which falls on the leaves and other greenish surfaces on plants are trapped. This trapped energy is converted to reserve energy in the form of food by a process known as photosynthesis.
What are some of the uses of visible light?
