Understanding the Refraction of White Light: Which Color Bends the Most?

The phenomenon of refraction occurs when light passes through a medium, such as a prism, and bends or changes direction. White light is made up of a combination of colors from the visible spectrum. In this article, we will explore the question of which color of white light bends the most when refracted by a prism. By understanding the properties of light and the concept of refraction, we can uncover the answer to this intriguing question.

1. The Nature of White Light:

White light is composed of various colors that make up the visible spectrum, including red, orange, yellow, green, blue, indigo, and violet.

Each of these colors has a different wavelength and frequency, which determines its position in the spectrum.

2. The Refraction of Light:

When white light passes through a prism, it undergoes refraction, which means it bends or changes direction. The amount of bending or refraction depends on the wavelength of light, with different colors experiencing different degrees of bending.

3. The Relationship Between Wavelength and Refraction:

The angle of refraction, or the amount of bending, is inversely related to the wavelength of light.

This means that shorter wavelengths (such as blue and violet) are refracted more than longer wavelengths (such as red and orange) when passing through a prism.

4. Examining the Colors: Red, Green, Yellow, and Orange:

In the context of the question, we need to determine which of the given colors (red, green, yellow, or orange) experiences the most bending or refraction when white light passes through a prism.

Red Light: Red light has a longer wavelength compared to the other colors mentioned. Due to its longer wavelength, it undergoes less bending or refraction when passing through a prism.

Green Light: Green light falls in the middle of the visible spectrum in terms of wavelength. It experiences a moderate amount of bending or refraction when passing through a prism.

Yellow Light: Yellow light has a slightly shorter wavelength compared to green light. Therefore, it bends more than green light but less than the shorter-wavelength colors.

Orange Light: Orange light has a shorter wavelength than red light but longer than yellow light. As a result, it bends more than red light but less than the shorter-wavelength colors.

When white light is refracted by a prism, different colors experience different degrees of bending or refraction due to their varying wavelengths. In the case of red, green, yellow, and orange, red light bends the least, followed by green, yellow, and then orange. This hierarchy is based on the relationship between wavelength and refraction. Understanding this phenomenon allows us to appreciate the unique properties of light and the fascinating behavior of colors when passing through prisms.
