'Cahaya adalah radiasi elektromagnetik yang dapat dilihat oleh mata manusia. Ia memiliki panjang gelombang yang bervariasi, biasanya dalam rentang 380 hingga 750 nanometer. Cahaya adalah sumber energi yang memungkinkan proses fotosintesis pada tanaman dan mempengaruhi penglihatan manusia. Dalam ilmu fisika, cahaya juga dapat dianggap sebagai aliran partikel yang disebut foton dan dapat berperilaku sebagai gelombang. Cahaya dapat dipantulkan, dib refraksikan, dan diserap oleh berbagai material.',
