Dispersive prism - Educational Model - Spectrum

I have designed a refractive prism to explain the spectral colours of light in an understandable way.How a prism works: A prism is an optical element that can direct light rays in different directions through refraction. The main physical principles behind how a prism works are refraction and dispersion: Refraction: when light passes from one medium into another (e.g. from air into glass), its speed is altered, causing the light beam to deflect at the interface. This effect is known as refraction. Dispersion: Different wavelengths (colours) of light spread out in a medium at different speeds. This results in the individual colours being deflected to different degrees. Short-wave light (e.g. blue and violet) is refracted more strongly than long-wave light (e.g. red).When white light enters a prism, it is refracted twice at the interfaces between air and glass: when it enters and when it leaves. The individual spectral colours become visible through dispersion and form the characteristic
