Where is light energy found?
The main source of light on Earth is the Sun.
Sunlight provides the energy that green plants use to create sugars mostly in the form of starches, which release energy into the living things that digest them.
This process of photosynthesis provides virtually all the energy used by living things..
What is light energy used for?
Light energy is used to help us see – either naturally using the Sun or fire, or with manmade objects like candles or lightbulbs. Light energy is also used by plants, which capture the light energy from the Sun and use it to produce their food.
What is light energy in simple words?
Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes. Light is defined as a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun.
What are the advantages of light energy?
Due to the fact that sun is the primary source of all light energy, all advantages associated with solar energy are inherent in the use of light energy. The most obvious advantage of using light energy is the fact that it is economically appealing. Light as a fuel is free of cost, and it will continue to be so.
What are 5 uses of light?
Uses of light energyIt helps us to see things.It helps plants to make food and grow.It is used in power satellites and space stations.It is used in many electronic appliances.The energy of light from the sun can be harvested to solar panels and can be used for domestic use since it is eco-friendly and cost effective too.
What are 3 sources of light energy?
Natural sources of light include the sun, stars, fire, and electricity in storms. There are even some animals and plants that can create their own light, such as fireflies, jellyfish, and mushrooms. This is called bioluminescence. Artificial light is created by humans.
How is light important?
WHY IS LIGHT MEASUREMENT IMPORTANT? Most importantly, light is used in photosynthesis, the process which produces food for all aquatic plants and most coral. … The human eye is very poor at judging light intensity as it is designed to work at very low and very high light levels without us knowing.
What is importance of energy?
Energy is very important in today’s world. For example, we use different energy sources to generate the electricity we need for our homes, schools, businesses and factories. Electricity powers our TVs, computers, air conditioners, cell phones and washing machines – just to mention a few.
What are 3 things that use the most energy in your home?

What is light energy and examples?
There are many example we see in our routine life carrying light energy like lightened candle, flash light, fire, Electric bulb, kerosene lamp, stars and other luminous bodies etc. Each act as a source of light. Even a burning candle is an example for light energy.
What are the different uses of energy?
We divide our energy use among four economic sectors: residential, commercial, transportation, and industrial. Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy.
What are the main uses of electricity?
People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems.
