Why does light change path when it changes mediums

A particle is moving in a straight line. at t second, it acceleration is (4-kt), where k is a constant. when t=6, the acceleration of a particle is zero determine its velocity as a function of time

When you hold a small amount of sodium chloride in a flame, you observe that the flame is bright yellow. What can you do to be sure that the color is due to sodium and not chlorine?
