A student placed a pencil in a cup of water. The pencil appears broken because light
always travels in a straight line.
bends when it passes through water.
makes the water in the glass evaporate.
reflects the pencil on the water's surface.
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.
Based on the image, as light passes from medium 1 to medium 2
light speeds up and bends towards the normal
light speeds up and bends away from the normal
light slows down and bends towards the normal
light slows down and bends away from the normal
19 degrees

What does the law of refraction state?
The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant called the refractive index.
The ratio of the sine of the angle of refraction to the sine of the angle of incidence is a constant called the refractive index.
The ratio of the sine of the angle of incidence to the sine of the angle of reflection is a constant called the refractive index.
The normal ray, reflected ray and incident ray all lie in the same plane.
