Monochromatic light is defined by having a single wavelength. This characteristic means that all the light waves present in the beam are of the same frequency and hence the same color. Since monochromatic light comprises only one wavelength, it does not contain the variations in wavelength that would be found in polychromatic light, which encompasses a range of wavelengths. This unique property of being monochromatic makes it particularly useful in various applications like laser technology, where precision and specificity in wavelength are critical for processes such as cutting, measuring, and medical treatments. Signals and interference patterns produced with monochromatic light are also more straightforward to analyze because there is no overlap from other wavelengths.
