Note: the dark patches do NOT indicate the absence of light. The dark regions merely represent 'troughs' of the waves and the light regions represent the 'crests'. The spots where the amplitude is zero will be :fuzzyj as they will have an amplitude of zero. 17. As you carefully observe the animation, how does the displacement (motion) of the particles in these regions differ? Click here to enter text. 18.
