Life exhibits color due to the wave-like nature of light. Waves, characterized by repetitive motion, have properties such as period and frequency. Light, being a wave, also possesses frequency, which determines its color. The visible spectrum ranges from red to purple, with each color corresponding to a specific frequency. Objects appear colored based on the light they reflect, with different colors being absorbed. Understanding these properties elucidates the phenomenon of color perception.
