Question
Read the paragraph from the article. All light shares three qualities: one, it can travel through a vacuum which is a space without any air or matter in it. Two it always moves at the same speed, which is 300,000,000 meters (186,000miles) per second in a vacuum . And three, the wavelength defines the type or color of light. Which statement BEST summarized the paragraph? Every type of light shares three qualities, which A include the fact that it can move through a space with no air. All different types of light move at B 300,000,000 meters per second, which equates to 196,000 miles per second. Light can travel through a vacuum, always C moves at the same speed, and its color is defined by its wavelength. Light can come in many different colors, and D the wavelength of light determines which color people will see.
