At first it may seem obvious but then I started to think what actually propells these to the speed they move?
If I radio through to my friend using a walkie talkie, what actually makes the radio wave travel at the speed at which it does?
The same when I turn on a laser pen or flip a light switch... Do these things build up speed or are they just instantly at there max speed?
