      of water which act as –
      A lenses Correct Answer Incorrect Answer
      B mirrors Correct Answer Incorrect Answer
      C prisms Correct Answer Incorrect Answer
      D slabs Correct Answer Incorrect Answer

      Solution

      In optics, a prism is a transparent optical element with flat, polished surfaces that refract light. In a rainbow, raindrops in the air act as tiny prisms. Light enters the raindrop, reflects off of the side of the drop and exits. In the process, it is broken into a spectrum just like it is in a triangular glass prism.
