A wavelength vs absorbance graph depicts in uv spectroscopy shows the different colored wavelenths of UV light and how they are absorbed and percieved, and which ones are visible and which ones are not.
The biodiversity graph depicts the variability of species in the given area.
Well, external calibration is a method used in analytical chemistry to determine the concentration of an unknown analyte. In essence, you take known concentrations of the analyte and plot it on an absorbance or transmittance graph to get a linear plot. And then you take that linear equation and plug in the absorbance or transmittance value received from the unknown solution and get the concentration. An example of this is if you want to find out the amount of calcium in a vitamin tablet. Dissolve the vitamin tablet and test the solution to get an absorbance value. Then test by the same method various concentrations of a calcium solution, plot this on a graph of absorbance vs. concentration and there yah go.
To prepare the standard curve you will need linear graph paper, semi-log graph paper and absorbance. You can define your standard curve by finding the absorption or percent plot on the Y axis.

To create an acceleration-time graph from a velocity-time graph, you need to find the slope of the velocity-time graph at each point. The slope represents the acceleration at that specific instant. Plot these acceleration values against time to get the acceleration-time graph.
In a graph, absorbance is typically shown on the y-axis and wavelength on the x-axis. The relationship between absorbance and wavelength is that as the wavelength of light increases, the absorbance generally decreases. This is because different substances absorb light at specific wavelengths, so the absorbance of a substance can vary depending on the wavelength of light being used.
A graph of absorbance versus concentration should pass through the origin because, according to Beer-Lambert Law, absorbance is directly proportional to concentration. When the concentration of a solution is zero, there are no absorbing species present, resulting in zero absorbance. This linear relationship indicates that as concentration increases, absorbance increases proportionally, reinforcing that the graph should start at the origin (0,0). Any deviation from this could indicate issues such as instrument calibration errors or scattering effects.

Chemists prefer to read the absorbance rather than the percent transmittance of light when analyzing a sample with a visible color because absorbance is directly proportional to concentration according to the Beer-Lambert Law. This allows for more accurate quantification of the sample's components. In contrast, percent transmittance may not provide a linear response and can be influenced by factors beyond just concentration, such as the color of the sample itself.

Absorbance is a measure of the amount of light absorbed by a sample at a specific wavelength, typically measured using a spectrophotometer. Concentration is the amount of a substance present in a unit volume of a solution, often expressed in moles per liter (M). The relationship between absorbance and concentration is governed by Beer's Law, which states that absorbance is directly proportional to concentration and path length.
UV Visible spectroscopy measures the response of a sample to ultraviolet and visible range of electromagnetic radiations. Molecules and atoms have electronic transitions while most of the solids have interband transitions in the UV and Visible range. Most molecules have a pi to pi* transition, involving pi electrons. The most important kind of UV/Vis Spectr. is Dispersion based spectroscopy. It involves a disperive medium like prism or grating to separate the different wavelengths.
A graph can be used to display almost anything. One of the classics is by Minard and depicts the losses suffered by Napoleon's army during his invasion of Russia. Another is by the first medical statistician, Florence Nightingale, and depicts deaths in the Crimea which supported the argument for an improvement of hygiene in military hospitals and thereby reduce fatalities.
To investigate absorbance versus time, you would typically measure the absorbance of a sample at regular time intervals using a spectrophotometer. This data can then be plotted on a graph to observe any changes or trends in absorbance over time, which can provide insights into the reaction kinetics or other time-dependent processes happening in the sample. It is important to ensure that the measurement conditions (wavelength, path length, temperature, etc.) remain constant throughout the experiment for accurate results.
