Answer:

Colorimeters are used in the range 400 nm - 800 nm.

Explanation:

In order to maximize accuracy, the colorimeter employs changeable optical filters to pick the wavelength that the solute collects the most. The wavelength range is typically 400 to 700 nm. If you need to work in the ultraviolet range, you'll need to make some changes to the colorimeter. The absorption of light waves can be measured using a colorimeter. The change in the strength of the visible portion of the electromagnetic wavelength part of the spectrum following transmission or reflection by an object or solution is evaluated during color measurement.

Thus, a colorimeter compares the light intensity going into a colored solution to the luminance shining through it.
