Which of the following statements regarding electromagnetic radiation is true?
A) Electromagnetic radiation with a wavelength of 400 nm travels faster than that with a wavelength of 600 nm.
B) The frequency of electromagnetic radiation determines how fast it travels.
C) Electromagnetic radiation with a wavelength of 400 nm has a frequency that is smaller than that with a wavelength of 600 nm.
D) Electromagnetic radiation with a wavelength of 600 nm travels faster than that with a wavelength of 400 nm.
E) Electromagnetic radiation with a wavelength of 600 nm has a frequency that is smaller than that with a wavelength of 400 nm.

Question

Quizplus · Accepted Answer

Electromagnetic radiation speed is constant in a vacuum, so wavelength and frequency are inversely related. A shorter wavelength (400 nm) means a higher frequency compared to a longer wavelength (600 nm).
