Homonym: light and dark (Contrast)
Light is a form of energy that allows us to see the world around us. It travels in waves and can be produced by natural sources like the Sun or artificial sources like light bulbs. Light can be reflected, refracted, or absorbed, creating various effects and colors that we perceive.
Darkness, on the other hand, is the absence of light. When there is little or no light, our surroundings become difficult to see. Darkness can create a sense of mystery or fear, but it is also essential for certain natural processes, such as the nighttime cycle, which allows many creatures to rest and rejuvenate.
