Visible Light Spectrum
In fact, light disperses into its color spectrum in a glass slab as well. We can notice this if we look at it in a specific manner. Before we begin, you should be familiar with refractive indices. They are not consistent.
They differ according to the frequency of light and hence the wavelength. White light is refracted twice as it passes through a glass slab or a glass prism. It goes from air to glass and then back to air. It slows down at the first occurrence of refraction and accelerates up at the second.
So, what occurs in a slab of glass? Because both surfaces are parallel, all light rays slow down and accelerate at the same pace. As a result, it seems to an onlooker that white light has entered and exited the slab. In a prism, however, the situation is different. Because the surfaces are not parallel to each other, the light rays emanating from the prism eventually travel a route that is distinct from one other, resulting in a scattered effect.
What is Dispersion of Light?
Dispersion of Light- Aren’t rainbows beautiful? Have you ever wondered how a rainbow comes to be? It is a basic physics phenomenon known as light dispersion. So, what exactly is light dispersion?
When white light is transmitted through a prism, it is split into seven component colors. A prism is a transparent optical device with flat, polished surfaces that refract light. Refraction of light refers to the change in the direction of propagation of light as it passes through a different medium.
