Light Physics Quiz

Light Fundamentals

• The speed of light in a vacuum is approximately 299,792,458 meters per second (m/s) or 186,282 miles per second (mi/s).

Refraction of Light

• When light passes from air into water, it bends or changes direction due to the difference in density between the two mediums, a phenomenon known as refraction.

Light Properties

• The primary colors of light are Red, Blue, and Green, often referred to as RGB, which can combine to produce a wide range of colors.
