Question

In each of these situations light refracts, except for one. Identify the case in which light is NOT refracted. A) a person wears glasses B) sunlight travels through space C) a magnifying glass enlarges an image Eliminate D) a fish is seen at the bottom of a stream

Answer 1

I say the answer is B) sunlight travels through space. for when the light refracts it bends by the change of speed of going through an object.

Answer 2

In cases A, B, and C, light slows down as it enters a different medium: glass in case A and B, and water in case C. However as sunlight travels through space and reaches the earth it travels without being blocked through a vacuum and is not refracted.
