AT A DEGREE CAN A PLANE MIRROR FORM A REAL IMAGE
When a narrow beam of sunlight is made to fall on a triangular glass prism, and a whitescreen is held on the other side of the prism, we observe a band of seven colour on thescreen. The colour sequence obtained on the screen from its lower end s given by famousacronym VIBGYOR.a) Define this phenomenon.b) Give any one example of dispersion of sunlight in nature.c) What value of life do you learn from this phenomenon?
