The precautions that must be taken during the experiment of transpiration
A photometer is used to measure the intensity of light or other electromagnetic radiation. It is commonly used in photography, astronomy, and environmental monitoring to quantify the amount of light present in a given area or to determine the brightness of objects.
A photometer used for measuring light intensity typically uses a lens that focuses the light onto a sensor or detector. The type of lens used can vary depending on the specific application and the desired level of accuracy or sensitivity required for the measurements.
A photometer is an instrument used to measure light intensity, therefore, the eclipsing binaries are best studied as we observe a periodic decrease of sunlight intensity as one member of the binary passes in front of the other.
The difference between the photometer and the spectrometer is a matter of complexity. Both are used to measure color absorbency quantitatively, but photometers are much simpler in design, having fewer parts, and as such are less expensive and easier to obtain. They're usually not quite as detailed in results as a spectrometer, however.
Depending on the size/importance of the experiment, they can either simply repeat as normal or if needed gather more resources for the experiments. Scientists always perform experiments at least three times, to make sure nothing is abnormal in an experiment.
Photometer is an equipment commonly used on a clinical laboratory. It has different kinds which can do certain jobs like testing blood samples. The examples of photometer used in a clinical laboratory are the flame photometer and Hemoglobin Photometer.
what are the principles behind LF Photometer
The flame photometer
unit of photometer
When doing a controlled experiment, you get accurate results.
tap water will evaporate the fastest. I know this because i did the experiment for school.
To get nutrients from the soil and enable to make glucose
if I put them in it for a few minutes while I do my experiment?

If you are referring to a the rate of water uptake in plants, then a live plant stem is placed in one end of the uptake photometer which is filled with water by a reservoir and tap. at the other end of the photometer there is a scale with an air bubble. Over time, as the plant takes in water, the air bubble will move along the scale and this can be used to work out how much water the plant is using. dont know if this will be of any help :)
