Pls help!! Question:
Write an evidence based explanation how differing the index of refraction, n, values affects how a light ray bends when transitioning from one medium to another. Your explanation should include the light ray traveling from 1) high index of refraction to low index of refraction and 2) low index of refraction to high index of refraction.
