What does God say about purpose?
Psalm 57:2 says, “I cry out to God Most High, to God who fulfills his purpose for me.” This is key in understanding God’s purpose for your life. God has numbered your days and will fulfill every purpose He has for you.
What is light exactly?
Light is a form of electromagnetic radiation with a wavelength which can be detected by the human eye. It is a small part of the electromagnetic spectrum and radiation given off by stars like the sun. Animals can also see light. The study of light, known as optics, is an important research area in modern physics.
Why do we see black?
Scientifically, color is an expression of light. Certain materials absorb and reflect specific wavelengths of visible light, which results in objects taking on a certain color to the human eye. When nearly all light is reflected, you see white. When no light is reflected, you see black.
What color cones do humans have?
The typical human being has three different types of cones that divide up visual color information into red, green, and blue signals.
How do we see Colour?
The human eye and brain together translate light into colour. Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of colour. Newton observed that colour is not inherent in objects. Rather, the surface of an object reflects some colours and absorbs all the others.
What causes color?
Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted. White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected.
How do we see?
When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals. These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.
What color does the human eye see best?
Green
