In the Visible spectrum of light, red color has the longest wavelength.

#### Explanation:

Red light has the least frequency among all other colors in the Visible spectrum of light.

Since Wavelength $\left(\lambda\right) \propto \frac{1}{\left(F r e q u e n c y \left(\nu\right)\right)}$,
$\therefore \lambda \propto \frac{1}{\nu}$.

Therefore, Red light has longest wavelength and hence traverses very large distances.

Here follows the Visible light spectrum in the order of increasing wavelength :
