Final answer:
A beam of white light is subjected to dispersion when passing through silicone flint glass due to the varying index of refraction for different wavelengths of light, resulting in a spectrum of colors.
Step-by-step explanation:
A beam of white light, when it passes through silicone flint glass, experiences different levels of bending for different wavelengths of light, due to the variation in the index of refraction. When white light enters a medium like silicone flint glass, where the index of refraction is 1.620 for red light and 1.660 for violet light, the light is subject to dispersion because each color of the spectrum bends at a different angle due to its own unique index of refraction. This effect causes the white light to spread out into a spectrum of colors, ranging from red to violet, similar to what is observed in prisms and rainbows.
