The sun is the source of virtually all energy on Earth. It heats the Earth and causes winds. It evaporates water allowing rainfall. It nourishes plants and all life dependent on them. The sun was created by God for the express purpose of supplying this life giving energy (light and heat) when it was created as the greater light on day four of creation week (Genesis 1:16).
The sunshine that warms you on your way to work in the morning reached your skin only 8 minutes after leaving the sun’s surface, roughly 93 million miles away (sorry but the sun does not revolve around the Earth, our solar system is heliocentric with the sun at the center and the earth and planets revolving around it). The sun releases many forms of energy. The total range of radiant energy released from the sun is known as the electromagnetic spectrum. The visible light (sunshine) we are familiar with forms only a small portion of the entire spectrum. The electromagnetic spectrum ranges from low-energy radio waves to high energy gamma rays. Visible light is about in the middle of this spectrum which can be broken down into colors by way of a prism. Interesting note, the concept of a prism comes from Job 38:24a, “By what way is the light parted:”
The energy that does the most damage is the energy that has the higher frequency and shorter wavelength such as ultraviolet rays, x-rays and gamma rays. The full electromagnetic spectrum goes like this, radio-waves, microwaves, infrared waves(heat), visible light, ultraviolet rays, x-rays, and gamma rays. This energy may be thought of as coming to Earth in a form of waves. The distance between two successive wave peaks is the “wavelength”. Both the level of energy and the wave frequency (number of waves per unit distance) increase from radio-waves to gamma rays end of the spectrum.
All the energy that powers activities of life, from the, growth of a pumpkin to the beating of the human heart, can be traced back to its original source, the sun. Sunlight energy is first captured by plants during “photosynthesis”, the process by which solar energy is used in the conversion of carbon dioxide and water into sugar. Oxygen is given off in the process and released into the air. With a few minor exceptions, this process can occur only in the presence of “chlorophyll”, a green pigment found in algae, some bacteria, and plants. In a sense, the solar energy is trapped by the chlorophyll and channeled into sugar molecules in the form of chemical energy. what a marvelous process God created to be utilized in plants. It is amazing that we give off carbon dioxide in our process of respiration which is utilized by the plant kingdom which uses it in photosynthesis and gives off oxygen. God created everything to be in order, not chaos (I Corinthians 14:40) and photosynthesis shows this order.
