Homonym: Light vs. Dark (Contrast)
Light and dark are fundamental concepts in physics and nature. Light refers to the visible spectrum of electromagnetic radiation that allows us to see the world around us. It travels in waves and can be produced by sources like the Sun, light bulbs, and fire. Light is often associated with clarity, warmth, and positivity.
In contrast, dark refers to the absence of light. It occurs when light is blocked or not present, creating shadows and obscuring visibility. Darkness can evoke feelings of mystery or fear, but it is also essential for processes like photosynthesis in plants, which rely on the cycle of light and dark for growth and energy.
