The indices of refraction for different colors of light in an acrylic prism vary slightly, with red light having a slightly lower index compared to blue light. This results in the dispersion of light into its constituent colors when passing through the prism, creating a rainbow effect. The overall index of refraction for acrylic is around 1.49-1.50, causing the bending of light as it enters and exits the prism.
The reason white light is separated into colors is because light of different colors have slightly different indices of refraction. Thus, for example, red light might be bent a little bit more than blue light.
No, the glass prism would not separate white light into its different colors if it is in a medium with the same index of refraction. The phenomenon of refraction and dispersion, which causes white light to separate into its constituent colors, occurs because different colors of light bend at different angles as they pass through a medium with varying refractive indices. If the medium has a uniform refractive index, there would be no bending of light rays, and thus no dispersion of colors.
Refraction. White light is a mix of colors in the first place; these colors have different indices of refraction. That is, when moving from air to glass, as in a prism, they will bend at slightly different angles.
Refraction of light occurs when light waves enter a medium with a different refractive index, causing them to change speed and direction. The amount of refraction depends on the wavelength of the light, with shorter wavelengths (such as blue) being refracted more than longer wavelengths (such as red). This dispersion of colors in a prism is due to the varying refractive indices of different wavelengths of light.
The indices of refraction for different colors of light determine how much each color slows down when passing through a medium. This causes the different colors to bend by different amounts, resulting in the separation of colors that we see in phenomena like rainbows or prisms. Each color has a specific wavelength, which interacts uniquely with the material's refractive index, leading to distinct paths of light.
Prisms create spectrum of colors by the cause of refraction.
Reflection happens only at the interface between two media, and two media with the same index of refraction act as if they were a single medium. Thus, at the interface between media with the same index of refraction, there is no reflection, and the ray keeps going straight. Continuing this line of thought, it is not surprising that we observe very little reflection at an interface between media with similar indices of refraction.
