I need help with my science review. I was sick for a lot of this so it's all new to me I will be updating the thread with more questions the farther I go. I'd really appreciate it guys! Q12: A light ray is travelling from a medium with a larger index of refraction to a medium with a smaller index of refraction. Describe what happens as the angle of incidence gets larger and larger. Include the concept of the critical angle in your discussion. Q16: A clear plastic cube with exactly the same index of refraction as water, is placed in a container of water. Would you be able to see the plastic cube in the water if you looked at it from an angle? Please explain why or why not.
