Based on the image, which medium has a larger index of refraction?
Medium 1 has a larger index of refraction.
Medium 2 has a larger index of refraction.
Both mediums have the same index of refraction.
Cannot be determined.
What happens to light during total internal reflection?
The light reflects back into the original medium at the same angle.
The light refracts closer to the normal line.
The light refracts farther away from the normal line.
The light reflects at the angle it would have refracted at.
What happens to the speed of light in a more optically dense medium?
it slows down
it speeds up
stays the same because all light travels at the speed of light
When will total internal reflection occur?
When light travels from a less dense to a more dense medium
When the angle of incidence is smaller than the critical angle
When the angle of incidence is greater than the critical angle
When the light cannot pass through a medium
