How do you find the frequency from wavelength?
To find the frequency from wavelength, you can use the formula: frequency speed of light / wavelength.
How do you find wavelength in pm units?
To find wavelength in picometer (pm) units, you can use the formula: wavelength (pm) = wavelength (in meters) * 1e12. Simply multiply the wavelength value in meters by 1e12 to convert it to picometers.
How do you calculate frequency when given a half wavelength?
To calculate frequency when given a half-wavelength, you first find the full wavelength by doubling the half-wavelength value. Then, use the formula frequency = speed of wave / wavelength to find the frequency of the wave.
How to find the frequency of a wave using its wavelength?
To find the frequency of a wave using its wavelength, you can use the formula: frequency speed of the wave / wavelength. The speed of the wave is a constant value, so you can divide the speed by the wavelength to calculate the frequency.
How do you find the shortest wave length?
To find the shortest wavelength, you would need to look for the highest frequency electromagnetic wave in the spectrum. You can use the formula: wavelength = speed of light / frequency to calculate the wavelength, with the highest frequency corresponding to the shortest wavelength.
In relation to spectroscopy what is the Optimum wavelength and how to find it?
The optimum wavelength is the wavelength by which the most light is absorbed by a substance. It can be found by finding the highest absorbance obtained when testing the substance's absorbance at various wavelengths. The wavelength that results in the greatest light absorbance is your optimum wavelength.
What is the specific absorbance of aspirin?
If you have a spectrofotometer ( the thing to mesure the absorbance) then play with the setting and use a maximum. this will lay close to your specific absorbance or take the pharmacopea or a MERCK index
What is the formula on how to find starch in water?
To find the concentration of starch in water, you can use a spectrophotometric method by measuring the absorbance of the solution at a specific wavelength. Prepare a standard curve using known concentrations of starch solutions to correlate absorbance with concentration. Then, measure the absorbance of your sample and use the standard curve to determine the starch concentration.
What is the optimum wavelength of light absorbed by chlorophyll and why?
The optimum wavelength of chlorophyll is 430nm (in a light spectrum of 380nm-750nm going in 10 incements) We did a lab and it required us to determine the optimum wavelength of chlorophyll by testing the absorbance of light in 10nm increments from 380nm-750nm. Optimum wavelength is the wavelength of light that is absorbed best by a substance. So when we tested all the wavelngths 380-750 in 10 increments (380,390,400,410,420....) 430 had the highest absorbance. we used a Spec 20 machine to find the absorbance.
How do you find the concentration of potato cells immersed in salt solutions?
You would have to use a spectrophotometer to measure the absorbance of your unknown solution. But first, you need to make several solutions with known concentrations. Measure the absorbance of the known concentrations and plot them on an X and Y axis where X equals concentration and Y equals absorbance. Do a best-fit line for your data. Measure the absorbance of your unknown solution. Find this value on your Y-axis and find out where this value intersects with your line of best fit. The X value at the intersection is your concentration of potato cells. By the way, make sure you use the same wavelength throughout the experiment.
