Would a temperature change affect the refractive index and if so, how?
Select the best explanation from those shown.
1) At higher temperatures, the liquid would evaporate and the refractive index could not be measured accurately.
2) Yes, a decrease in temperature would decrease the refractive index.
3) Yes, a decrease in temperature would increase the refractive index.
4) No, the refractive index is temperature independent.
anyone has any idea?thank you.

As the liquid cools it becomes denser and light bends more, giving a higher refractive index.

Refractive Index is temperature dependent where they are measured at 20 Celsius. Most RI instruments have a way to keep the crystal at a constant temperature with water for this reason.

I agree. Most substances shrink when cooled, becoming denser. This generally raises their index of refraction (a measure of 'optical density').
