Which of these characteristics can only be attributed to a wave of red light? a) the energy of the wave travels in the same direction as the wave travels. b) the wave travels by vibrating the particles of the medium at a high rate. c) the wave travels by compressing and expanding the medium it travels through. d) the energy of the wave moves perpendicular to the direction the wave travels.
The energy of the wave moves perpendicular to the direction the wave travels.
I had this question on USA test prep and this was the correct answer
Electromagnetic waves are transverse waves. Visible light consists of red light which is also an electromagnetic light. Thus red light particles vibrate perpendicularly to the direction of wave 's motion
