ライト (Light) is a form of electromagnetic radiation that is visible to the human eye. It travels in waves and can be described by its wavelength, frequency, and energy. Light is essential for vision, as it allows us to see colors and shapes in our environment. In addition to its role in vision, light plays a crucial part in various natural processes, such as photosynthesis in plants. This process enables plants to convert light energy from the Sun into chemical energy, which is vital for their growth and for producing oxygen, benefiting all living organisms on Earth.
