What is the effect of increasing the temperature on the refractive index of a medium?

Step 1: Understand what refractive index means. It is a measure of how much light bends when it enters a medium.
Step 2: Know that temperature can affect the properties of a medium, such as its density.
Step 3: Realize that when the temperature of a medium increases, its density usually decreases.
Step 4: Understand that a lower density means that light travels more easily through the medium.
Step 5: Conclude that as the temperature increases, the refractive index of the medium decreases because light bends less.
