Dependent variable is the angle of refraction. Control variables are the material of the block, the shape of the block and the colour of the light. Remember - these variables are controlled (or ...

In general, the refractive index varies based on the frequency of the light as well, thus different colors of light travel at different speeds. High intensities also can change the refractive index.
