Which of the following colours of light is refracted the most?Group of answer choicesvioletredgreen

1. Break Down the Problem

To determine which color of light is refracted the most, we need to understand how the refractive index varies for different wavelengths of light.

2. Relevant Concepts

• Refraction: Refraction is the bending of light as it passes from one medium to another with a different density.
• Refractive Index: The refractive index ($n$) of a medium is defined as the ratio of the speed of light in vacuum to the speed of light in the medium.
• Wavelength and Refraction: Shorter wavelengths (like violet light) are typically refracted more than longer wavelengths (like red light) because they have higher refractive indices in most media.

3. Analysis and Detail

In general:

• Violet light has a shorter wavelength (about 380–450 nm).
• Green light has a medium wavelength (about 495–570 nm).
• Red light has a longer wavelength (about 620–750 nm).

Given that violet light has the shortest wavelength among the options, it generally experiences a greater change in speed and direction as it enters a new medium, such as glass or water, thus being refracted more than the other colors.

4. Verify and Summarize

On evaluating the wavelengths and understanding the principles of refraction, it can be confirmed that violet light is refracted the most compared to red and green light.

Final Answer

Violet light is refracted the most among the choices provided.
