Question

Are there any exceptions to the inverse relation between refractive index of a medium and the temperature?

Answer 1

Answer:

Yes, there any expectation to the inverse relation between refractive index of a medium and the temperature

Answer 2

Explanation:

Thus, the index of refraction normally decreases as the temperature increases for a liquid. For many organic liquids the index of refraction decreases by approximately 0.0005 for every 1 °C increase in temperature. However for water the variation is only about -0.0001/°C.
