![]() In other words, the higher the temperature, the lower the refractive index, as shown in the graph below which uses water as the sample medium.Īs you can see, the sample temperature has a major influence on the measurement procedure. If a medium is less optically dense due to a temperature increase, the light will travel faster, which causes the deflected angle to shift slightly. Atomic vibration increases as temperature increases, which causes the atoms to move farther apart and reduces the optical density value of the sample medium.Īs noted previously, the refractive index describes how fast a light beam travels through media. Temperature influences the space in which atoms fit together to create a molecule. So what is the relationship between refractive index determination and temperature?įirst, we need to understand the effect of temperature on a liquid sample.
