Answer
## 1. When light traverses a prism, it's refracted -- or bent -- and as a result, it disperses into its component wavelengths (colors). This array of colors that emerge from the prism is termed as a spectrum.## 2. In a rainbow, which is a natural spectrum, the progression is Red-Orange-Yellow-Green,-Blue-Indigo-Violet (ROYGBIV).
Explanation
## Step1: To begin, this question is intended to evaluate our knowledge of the properties of light and how it interacts with certain objects like prisms and rainbows, which are natural phenomena that display spectrum of light.## Step2: The first question ponders what transpires when a spectrum of light passes through a prism. This process is known as spectrum analysis. Nothing other than base knowledge is required here; it's a direct question without further calculations necessary.## Step3: The second question delves into the particular colours and their arrangement as observed in a rainbow. Rainbows form due to reflection, refraction, and dispersion of light in droplets of water — producing a spectrum of colours taking certain order commonly remembered with the acronym ROYGBIV (Red, Orange, Yellow, Green, Blue, Indigo, and Violet).
