light energy is energy produced or emitted light source. as we know, the Sun is the source of energy lighting greatest in the world. as for example of this energy is the Sun, fire, stars, electric lights, candle, flashlight, lightning and others. in the presence of this energy then when we are in dark place will look light. sometimes energy is also referred to as solar energy because it is actually the source of information derived from the solar power or the Sun. Sun emit most of the radiation called electromagnetic. while human own can only see some of his course of the energy this one, which is known as "the visible light". light energy own can be defined as energy in the form of an electromagnetic waves that has the wavelength of 380 to 750 Nano meters based on the invisible. light energy matahari light own a package particles by the name of photons.
study of light initiated by the emergence of the time of optics classic to learn about the amount of optical, such as phase of light, polarization, wavelength, the frequency and intensity. Sun as a source of the light energy largest, have a very important role for human life in the world, among others: 1. help the process of photosynthesis sunlight is a major source of life living beings, one is life for plants or plants to help the process of photosynthesis. the absence of the Sun own, then the plant or plants on Earth will die. as lead behind it, when there is no plants in the Earth is the man will disappear due to lack of oxygen supply of herbs. can we conclude that the life cycle living things including human own so depending on the Sun. photosynthesis process plant own will result in oxygen, which is very important for respiratory humans. so, human life also depends on the intake of oxygen inhalation. it is reasonable, if the Sun in this role is so important as well with the role of water to human life. 2. help lighting the absence of sunlight, the world will dark. so that we will not be able to see anything that is in the environment around US. in the presence of energy solar light of this, then we can see the environment. therefore, the light is very important role as a media lighting. in addition to sunlight, light of the light is also serves as lighting at night. light of the light is also help you to be able to study at night. 3. sunning clothes in the presence of sunlight own, then clothing washed can directly dry without dryer. sunlight as media for drying clothing easily and natural, with the help here's clothing will easily dry current drying under the blazing Sun. wear the help of the Sun is certainly not need to pay expensive to buy a washing machine at once dryer clothes, as the Sun this we can get for free. 4. produce electrical energy as a source of light, Sun can also produce electricity. electrical energy this is what will be used to light in the evening. in addition with electric energy, we can use electronic and tools households with comfortable. electrical energy from the help of the Sun or solar cells is certainly more environmentally friendly. not only that only, Sun also including renewable energy supply is not limited. 5. help growth process sprouts in addition to benefit the human life, light energy is also very useful for plants. if sprouts shortage of light, then the plant will dry, petite, leaves pale yellow and thin. different from the sprouts enough sunlight, then the plant will have the leaves thick, Green and flourish. this is because sprouts will be more maximum in the process of photosynthesis to produce the food and substance of energy. 6. as a source of the best nutritional benefits light energy next is as a source of nutrients best. on a trial, plants stored in the enclosed space with the help of artificial light, have energy and nutrition poor not as good nutrition and energy generated by direct sunlight. 7. help the growth of interest and leaves the next is light energy can help the growth of interest and also leaves. as you know the wavelength of solar energy has warnamerah. Red color that is in a wave of the Sun will be absorbed by plants in the end this will have an impact on the growth of interest. so plant often exposure to sunlight will quickly flowering and grow high as well as heavy. 8. keep the temperature of plants sunlight can also keep the temperature of plants to stay balanced and stable. if the temperature of plants low then evaporation process will be a long time, it is of course can make plants suffocate. and vice versa if the temperature is too high then evaporation process will be accelerated. this will cause the plants to dry. 9. dry land on some plants, sunlight is very useful in the process of breeding. sunlight is required in the process of drying the ground. so flower seeds that fell to the ground dry will thrive. for example the sunflower seeds. However, no means sunflower seeds could not grow on the ground humid, but it will quickly Wilt and will eventually die.
Benefits of Solar Energy
Benefits of Solar Energy For Humans
Solar Energy As A Power Plant
On the previous occasion I already discussed about the benefits of water for hydroelectric (hydropower). Well on this occasion do you know that the sun that every day we feel its existence can be used as a powerhouse? Maybe someone already knows and some do not know yet.
In today's modern era, inventions after discovery have been widely developed in technology. Among the inventions that have been developed is the process of changing solar energy into electrical energy that is very helpful to humans to cover secondary needs such as: lighting the house with lights, watching television and various things that use electricity.
Solar Energy For Bone Health
For those of you who have a baby and a newly completed oprasi, sunbathing in the sun at 07:00 to 08:30 in the morning can nourish your body especially in the bones because the sun's energy in that hour can produce Vitamin D by changing pro vitamin D in body. So do not be surprised if many parents who take their baby to sunbathe in the morning because it is very helpful for the baby in the process of growing his bones.
As Unlimited Energy
Source of energy sourced from Fossil be it fossil animal or plant fossil, one day will experience run out if in use continuously. But unlike the case with the source of solar energy that will never run out even in continuous use by all living things on earth.
Solar Energy For Drying Process
Can we imagine if there is no sun, what would happen with dirty clothes that you just washed. one day just overcast skies, not a few mothers who complain because wet clothes do not go dry so as to produce odor.
Solar Energy As Pain Post Oprasi Disease
A renowned University has conducted research on solar energy to aid the post-oppression process of people and the results are staggering. Post-oprasi pain can gradually disappear when the patient routinely sunbathe in the sun with a patient who every day just stays in the room.
Benefits of Solar Energy for Animals
To Warm Up The Body
There are some animals that use solar energy as a means to warm their bodies, such as snakes, lizards, birds and many other animals that use solar energy to survive.
To Digest Food
Not a few animals that are naturally have bad digestion, so to digest the food that he ate, certain animals use heat from the sun by way of sunbathing so that the food can be quickly digested.
Strengthens Bones
Not only humans who want to have strong bones, animals must have strong bones because without a strong bone an animal will be easily sick and will be difficult in finding food.
