What are the wavelengths of the peaks in each color matching curve in
Fig. 9.18

**Figure 9.18**: The CIE color-matching functions (Public domain via Wikimedia Commons) This figure illustrates the CIE color-matching functions, which are fundamental tools in the study of color vision. The graph consists of three curves representing the color-matching functions for the human eye: 1. **Red Curve (\( \overline{x}(\lambda) \))**: This curve is depicted in red and indicates the sensitivity of human vision to red light across different wavelengths. It peaks around the lower to mid-600 nm region, which corresponds to the red part of the visible spectrum. 2. **Green Curve (\( \overline{y}(\lambda) \))**: Shown in green, this function marks the sensitivity to green light, peaking around the mid-500 nm area, highlighting the central region of the visible spectrum. 3. **Blue Curve (\( \overline{z}(\lambda) \))**: This blue line shows the sensitivity to blue light, peaking towards the lower end of the spectrum around the 400-500 nm range. The x-axis represents the wavelength in nanometers (nm), ranging from 400 nm to 700 nm, covering the visible spectrum. The y-axis indicates the relative sensitivity of the color-matching functions. Understanding these functions is essential for color science, allowing the precise depiction of colors in technologies such as monitors and printers.
