Final answer:
Our perception of color is dependent on the wavelength of light, with different wavelengths corresponding to different hues, leading to the diverse array of colors we see, exemplified by the separation of white light into a rainbow.
Step-by-step explanation:
Our perception of the color is largely dependent on the wavelength of the light that hits our retinas. Wavelength correlates with the hue we perceive; with light at the red end of the spectrum having longer wavelengths and lower frequency, while light at the violet end has shorter wavelengths and higher frequency. The wavelength of light is critical in determining the color we see, as humans perceive light within the range of approximately 380 nm to 740 nm. Moreover, objects can reflect different wavelengths, which our eyes ultimately interpret as colors.
For instance, when white light passes through a prism, it is refracted and separated into a spectrum of colors from red to violet, this separation is due to the fact that light of different wavelengths bends varying degrees upon refraction, a phenomenon known as dispersion. As a result, this wavelength-based separation is what contributes to the vibrant hues we see in a rainbow. Understanding these concepts is essential for grasping how and why we perceive different colors in our environment.
