In IR spectroscopy, transmittance is often plotted because it provides a direct measurement of how much infrared light passes through a sample compared to the incident light. This approach aligns with the common practice of measuring the intensity of transmitted light, making it easier to visualize and interpret spectra. Additionally, transmittance values range from 0 to 100%, which can be more intuitive for understanding the sample's interaction with light, whereas absorbance values can vary widely and may not be as straightforward to interpret.

Why is absorbance plotted instead of percent transmission when following bacterial growth?
Absorbance is typically used in bacterial growth studies because it provides a linear relationship with cell density over a wider range compared to percent transmission. This allows for a more accurate and sensitive measurement of bacterial growth at different stages. Additionally, absorbance is less affected by small variations in sample volume or path length, making it a more reliable measurement parameter.
How to calculate lambda max?
using uv-visible spectrophotometer concentration vs absorbance is plotted and the maximum absorbance of the drug is lambda max of the drug. then after it will decrease. still if needed clarification, refer beer lambert"s law
What is plotted on the horizontal x axis while distance is plotted on the vertical y axis?
On the horizontal x-axis, the independent variable is typically plotted, and on the vertical y-axis, the dependent variable is plotted. The x-axis represents the input or factor that is being tested or manipulated, while the y-axis represents the output or result that is being measured or observed.
What is cylindrical projection?
It's a geometrical technique for plotting the 3D spherical shape of the Earth onto the 2D, flat, plane surface of the map. In most forms it imagines the map sheet is rolled into a vertical cylinder of diameter (scaled) = Earth's scaled diameter, so tangential to the globe all the way round the Equator. This means the longitudes will be accurate along the Equator, but the latitudes will be increasingly inaccurate with increasing angle North or South if plotted at equal intervals. Therefore the latitude lines are plotted at increasing spaces N & S, to correct for the error. Now, a moment's thought will show that if the longitude lines are plotted on a circumferential pitch (linear distance) at the Equator they will be hopelessly out as the plot approaches the poles. So the longitudinal, or Equatorial, axis is plotted in angle increments: still not correct but the better option. It is something of a fudge but projecting irregular shapes littering the surface of an oblate spheroid onto a rectangular plane can only be an exercise in minimising approximations!
When graphing enthalpy and entropy what variables are included?
Temperature and energy are two of the variables included when graphing enthalpy and entropy. Enthalpy is made up of the energy, pressure, and volume of a system. Entropy is a way to determine the different ways energy can be arranged.
Why don't you plot transmittance vs wavelength?
Sometimes you do in fact. In IR spectroscopy, the transmittance is commonly plotted instead of absorbance.However, in most types of spectroscopy, the absorbance is plotted instead. This is due to Beer's Law, which states that the absorbance is directly proportional to the concentration of the sample, the absorptivity of the sample, and the path length (in contrast, the transmittance is exponentially related to those things). Because of the much simpler direct proportionality, absorbance is preferred in many cases.
Why do peaks in IR are negative?
In infrared (IR) spectroscopy, peaks appear negative due to the way the instrument measures absorbance. The IR spectrum is typically plotted as transmittance (percentage of light transmitted) versus wavenumber or frequency. When a sample absorbs IR radiation, less light reaches the detector, resulting in a decrease in transmittance, which is reflected as a negative peak on the spectrum. Essentially, the negative peaks indicate specific frequencies at which the sample has absorbed energy.
When you graph linear equations by plotting points the points you plot should all be what?
... plotted accurately.
Who was the Chinese emperor who killed his mother and brother after he found out they were plotting against him?
Shi Huangdi killed his two brothers and exiled his mother after he found out they plotted to assassinate him.
How do you investigative absorbance versus time?
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.
Why is absorbance plotted instead of percent transmission when following bacterial growth?

This allows for a more accurate and sensitive measurement of bacterial growth at different stages.

How do you get a slope and a linear function?
plotting a slope means plotting a graph of y against x.to get the linear function ,the only thing to do is to know whether the value of y and the equivalent value of x at the point if its a well plotted slope normally any choosen point will be the same .assuming it is not a curve.if not replot.

The name for the group of individuals who are plotting the overthrow of julius caesar?
The name for the group of individuals who plotted to overthrow Julius Caesar depends on your source. Some, such as those called "populares" would call them Conspirators while the hard line republicans, the Optimates, would call them Liberators.
Is a demand curve created from a demand schedule?
The data on a demand schedule can be plotted on a demand curve. Often, a demand schedule will be created before the creation of a demand curve, so as to allow for greater accuracy when plotting the demand curve.
What is a sentence for the word plotted?
The group plotted to rob the bank.The plotted out the design for the new building.Guy Fawkes plotted to blow up the Parliament, but luckily failed.
What is plotted on the y axis?
Normally, the dependent variable is plotted on the y-axis and the independent variable is plotted on the x-axis.
