Final answer:

The statement 'Black light contains all the colors' is not a characteristic of light. Black light usually refers to ultraviolet light and does not contain all visible colors.

Step-by-step explanation:

You asked which of the following is not a characteristic of light:

  • a. Light is a transverse wave
  • b. Light can be sorted by wave
  • c. A particle of light is called a photon
  • d. Black light contains all the colors
  • e. The speed of light in a vacuum is 186,000 miles/second

The statement that is not a characteristic of light is d. Black light contains all the colors. In fact, 'black light' usually refers to ultraviolet light and does not contain all colors visible to the human eye. Instead, it can cause fluorescent materials to emit visible light. All other statements are true characteristics of light: light is indeed a transverse wave (a), a particle of light is known as a photon (c), and the speed of light in a vacuum is approximately 186,000 miles per second or 3 x 108 meters per second (e).
