Which of the following is true regarding red and blue light? select one: a. a. they travel at different speeds in a vacuum. b. b. only red light creates an interference pattern. c. c. only blue light creates a diffraction pattern. d. d. photons from blue light have more energy. e. e. both blue light and red light have the same wavelength.

Only D) is true, the rest are false.

Explanation:

A) False. Light travels at 299792458m/s in a vacuum, no matter color.

B) False. Every wave can cause an interference pattern.

C) False. Every wave can cause an diffraction pattern.

D) True. E=hf, and blue light has higher frequency than red light.

E) False. Since blue light has higher frequency than red light, it has shorter wavelength.
