Chapter 7: Light and Other Electromagnetic Waves

What is the relationship of light to the rest of the electromagnetic spectrum?

What is refraction and what is its role in image formation?

What is the connection between lens focal length and lens strength?

What does the optometrist measure when he/she writes a lens prescription?

How do you determine the focal length? The image position?

How are images formed by mirrors?

What is happening when a person is nearsighted? farsighted? How are these common eye defects corrected?

How does the eye accomodate for close vision?

How does the eye compare to a camera?

How can you predict the result when two colors of light are mixed?

How does a prism separate light into its component colors?

What properties and behaviors of light lead us to believe that they are composed of waves?

What is color? What properties of light are associated with color?

What causes the colors we see emerging from a prism? What causes the colors of the rainbow?

What other color and light phenomena in the sky appear to be wave phenomena?

How do polaroid sunglasses work? Is polarization a wave phenomenon?
