Why is it advisable to correct the measured refractive index for temperature?
Wiki User
∙ 15y ago
The refractive index is a physical property of the medium that depends on the wavelength of the light, and the temperature. The temperature needs to be specified, and is usually 20 or 25 degree Celsius. The refractive index decreases with increasing temperature, and for most organic compounds one can correct for the temperature.

∙ 11y agoTypically increasing the temperature of a medium reduces its density (e.g. by increasing the kinetic energy of each constituent particle). As the refractive index is dependent upon materialistic density, it is thus a function of temperature.

Correct units to determine specific heat?
Specific heat is the heat required to raise the temperature of a unit mass by one degree. It is measured by joules.
What do you need to know to decide whether this statement is correct?
the temperature of the water and the solubility of baking soda at that temperature
Which property is a measure of the average kinetic energy of the particles in a sample of matter?
Temperature is the correct answer because temperature measures average kinetic energy.
Does doubling celsius temperature double pressure?
Using the Celsius temperature scale, it is not correct. But doubling the temperature using the Kelvin temperature scale, where zero is the absolute minimum gegree possible, will double pressure . p1/T1=p2/T2=constant.
Can carbon be a gas?
Yes most things can be a gas as long as there at the correct temperature so carbon could be a gas
How do you spell temperatures?
Temperature is the correct spelling.The correct spelling is temperature (measured heat energy of an object or system).m,you mean temperature?
How do you spell tempuater?
The correct spelling is "temperature" (measured heat level).
What values can not be measured using SI units a. length b. density c. temperature d. all of the above?
The correct answer doesn't appear in the list of choices.Each of those three quantities CAN be describes in SI units.
What is the correct temperature for a wok?
The correct temperature is dependent on what you are cooking, not what you are using to cook it!
What is the correct transmission fluid level in a 2006 dodge sprinter van?
The correct fluid level is determined with the use of the dealers scan tool and the dipstick ( which is a special tool ). The scan tool is required to know internal trans temperature, That is compared to a chart and the correct fluid height can then be measured.
How do you correct refractive index to 20 c?
by using the prism spectrometer,we can easily find the refractive index of the material.

That would be correct,
How do you spell advise?
That is the correct spelling of "advise" (to counsel or suggest).The noun form is advice.
Can a truck be measured in meters?
The answer is yes because centiMeters is not correct
Why is there no dipstick to check the transmission fluid on the 2008 chrysler town and country?
The fluid level is very temperature specific. A scan tool is required to know the exact temperature of the fluid. The fluid level is then measured with a special tool ( at the dealer ) and that reading is compared to a chart in the service manual to fins the correct level. From a temperature of 30 deg F to 200 deg F the level can change 3 to 4 inches.The fluid level is very temperature specific. A scan tool is required to know the exact temperature of the fluid.

What does wavefront surgery correct?
The wavefront surgery corrects eye vision. It is used to correct refractive errors near sightedness, far sightedness and astigmatism. It is used to give people better eye sight.
