Question

which radiation source is used for colorimeter

Answer 1

Photoelectric colorimeter

Explanation:

• If a photocell instead of the eye is used to test intensities, the instrument is known as a photoelectric colorimeter. In colorimetry, frequently the whole spectrum white light is used, and consequently the complementary colour of the one absorbed is observed as transmitted light.
• During colour measurement the change within the intensity of electromagnetic waves within the visible wavelength region of the spectrum after transmitting or reflecting by an object or solution is measured.
• Photoelectric colorimeter has the components like a source of light. An example is an incandescent lamp with a tungsten filament.

Answer 2

Radiation source used for colorimeter:

• In colorimetry, the entire visible spectrum (white light) is frequently used, and as a result, the complementary colour to the one absorbed is observed as transmitted light.
• A colorimeter is a colorimetric device that measures the absorbance of specific wavelengths of light determine the concentration of a known solute in a given solution by applying the Beer–Lambert law.

Hence, the answer to the given question is as mentioned above.
