In this experiment, optical density is measured using a spectrophotometer.
- The spectrophotometer is a device that calculates how much light a substance absorbs.
- The spectrophotometer measures the light intensity of a sample by passing a light beam through it.
- Based on the Beer-Lambert rule, spectrophotometers may determine a solution's concentration by measuring the light intensity with wavelengths.
- A spectrophotometer is a device that counts the number of photons (light's energy) absorbed after they have passed through a sample solution.
- By measuring the intensity of light detected, the spectrophotometer may also estimate the quantities of a known chemical compound.
