As light slows down, it bends or refracts. The index of refraction helps predict the amount of bending. How are the
speed of light and the index of refraction related?
The speed of light is a constant in all materials.
The index is proportional to the speed of light in the medium
The index is inversely proportional to the speed of light in the medium.
The index is proportional to the square of the speed of light in the
medium.

Employer informs its employees that it will hold a substantial cash prize drawing for each work group at the end of each month in which no employee in the work group sustains a lost-time injury. tyra reports an injury that she sustained while operating a mechanical power press. tyra did not violate any employer safety rules when she sustained her injury. tyra’s injury requires her to miss work for two days. her employer cancels the cash prize drawing for that month for tyra’s work group because of tyra’s lost-time injury. did the employer misuse an incentive program to retaliate against tyra?
