Question

using beer lambert law . determine which of the following is either an independent variable or dependent variable.

concentration of photons vs absorption

absorption of varies colors

Answer 1

The dependent variable is the variable in the experiment, which is being measured and observed by the investigator. The dependent variable responds to the changes in the independent variable. As the name suggests, the dependent variable and its results depends on the independent variable, and it cannot exist independent of the independent variable.

1 ) concentration of photons : independent variable.

absorption : dependent variable .

2 ) absorption of varies colors : dependent variable .

Colours : independent variable .

The Beer-Lambert law relates the attenuation of light to the properties of the material through which the light is traveling.

The Beer-Lambert law (or Beer's law) is the linear relationship between absorbance and concentration of an absorbing species. The general Beer-Lambert law is usually written as:

A = a() * b * c

where A is the measured absorbance, a() is a wavelength-dependent absorptivity coefficient, b is the path length, and c is the analyte concentration. When working in concentration units of molarity, the Beer-Lambert law is written as:

A = * b * c

where is the wavelength-dependent molar absorptivity coefficient with units of M^-1 cm^-1.
