True or False: The angle of incidence of a light ray is equal to the angle of refraction
What is false.
100

This focuses light in both cameras and eyes

What are lenses

100
Light rays travel in...
What is straight lines.

What is bioluminescence.
400
In order for an image to appear on a surface, the surface must be what?
What is smooth/reflective.
400

A car catching a tire in gravel on a road is an analogy that can be used to describe this in refraction.

The slowing down of light rays in a different medium.

400

These capture the image seen in eyes and cameras

400

The imaginary line that extends up 90 degrees from the surface of a reflective object

What is the normal line.

500
The Law of Reflection states that these two things are equal.
What is the Angle of Incidence and the Angle of Reflection.

500

These are able to pick up red, green, and blue in our eyes.

What are cones

500
The four properties of light
What is 1. travels in straight lines, 2. can bend, 3. can be reflected, and 4. is a form of energy.
