[Sticks]

It occured to me that the smilie might be bouncing at a different rate to the smilie.

Is that the case ?

If not, suppose with these two side by side


If they commence to bounce as soon as this page is loaded, how long before they have a synchronised bounce. What would be the time interval between synchronised bounces ?

It reminds me of something we used to do in A Level Physics called Beat Frequency which occurs when you have two slightly dissimilar tones sounding close to each other. They interfere with one another and a separate wave form is created called the beat frequency. This would be observed as a sinosoidial increase and decrease in the volume of the two tones as they cancel and reinforce each other.

I wondered if it would be the case with

In other words I need to get out more
