Flame photometers work by separating the chemical sample into a constituent atoms and molecules. Then colors are emitted do to the chemicals as they absorb then release energy.
Yes. A photometer is an instrument that measures the intensity of the incoming light and quantifies it into numerical data. A photometer is a light sensitive device and measure the power of light.
Potassium ions produce a lilac flame in a flame emission photometer. The presence of potassium in a sample can be detected by observing this characteristic color emission when the sample is introduced into the flame.

A spectrophotometer consists of two instruments, namely a spectrometer for producing light of any selected color (wavelength), and a photometer for measuring the intensity of light. The instruments are arranged so that liquid in a cuvette can be placed between the spectrometer beam and the photometer. The amount of light passing through the tube is measured by the photometer. The photometer delivers a voltage signal to a display device, normally a galvanometer. The signal changes as the amount of light absorbed by the liquid changes. If development of color is linked to the concentration of a substance in solution then that concentration can be measured by determining the extent of absorption of light at the appropriate wavelength. For example hemoglobin appears red because the hemoglobin absorbs blue and green light rays much more effectively than red. The degree of absorbance of blue or green light is proportional to the concentration of hemoglobin. When monochromatic light (light of a specific wavelength) passes through a solution there is usually a quantitative relationship (Beer's law) between the solute concentration and the intensity of the transmitted light, that is, I=I010-kcl where I sub 0 is the intensity of transmitted light using the pure solvent, I is the intensity of the transmitted light when the colored compound is added, c is concentration of the colored compound, l is the distance the light passes through the solution, and k is a constant. If the light path l is a constant, as is the case with a spectrophotometer, Beer's law may be written, I/I0=10-kc=T where k is a new constant and T is the transmittance of the solution. There is a logarithmic relationship between transmittance and the concentration of the colored compound. Thus, -logT=log1/T=kc=optical density The O.D. is directly proportional to the concentration of the colored compound. Most spectrophotometers have a scale that reads both in O.D. (absorbance) units, which is a logarithmic scale, and in % transmittance, which is an arithmetic scale. As suggested by the above relationships, the absorbance scale is the most useful for colorimetric assays.
No, salt and sugar crystals are not commonly used to identify colors in paint. They are more commonly used in chemical experiments or culinary applications. Color can usually be identified in paint through visual observation or by using color matching tools.
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.

It is an instrument for measuring the intensity of light.
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 :)
The brightness of light produced by a source can be measured using a device called a photometer or lux meter. These tools measure the illuminance of light in lux, which is a unit of measurement for the amount of light that reaches a surface. By placing the photometer at the location where the light is being emitted, you can quantify the brightness level.
The tap in a photometer experiment is important to control the flow rate of the liquid being measured. By adjusting the tap, researchers can regulate the amount of liquid passing through the photometer, which impacts the accuracy of the measurements taken. It allows for precise control over the sample volume being analyzed.
