Answer the following question given this paragraph: Total internal reflection occurs when light goes from a slow (high index of refraction) medium to a fast (low index of refraction) medium. With total internal reflection, light refracts so much it actually refracts back into the first medium. This is how fiber optic cables work: no light leaves the wire. Q: When does internal reflection occur? Choices: - when light goes from a slow medium to another slow medium - when light goes from a fast medium to a slow - when light goes from a fast medium to another fast medium - when light goes from a slow medium to a fast A:
when light goes from a slow medium to a fast
