When white light passes through a prism, it is dispersed into its constituent colors, creating a spectrum. This occurs because different colors (wavelengths) of light are refracted, or bent, by different amounts as they pass through the prism.
White light splits into different colors when it passes through a prism due to a process called dispersion. Each color in the white light spectrum has a different wavelength, and when these wavelengths pass through the prism, they are refracted by different amounts. This causes the light to spread out into a spectrum of colors, from red (least refracted) to violet (most refracted).
The order of colors seen when white light passes through a prism is red, orange, yellow, green, blue, indigo, and violet. This sequence is often remembered by the acronym ROYGBIV.
A prism creates a spectrum of colors rather than just bending the light because different wavelengths of light are refracted by different amounts. This variation in refraction angles separates the white light into its component colors, each of which emerges at a different angle, forming a continuous spectrum.
Not all types of light will create a visible spectrum when passed through a prism. For example, monochromatic light, which consists of a single wavelength, will not be dispersed into multiple colors. Only polychromatic light, like white light, which contains multiple wavelengths, will produce a spectrum when passed through a prism.
