WebA laser pointer typically has a power rating of 1 mW, or 0.001 Joules per second. This means that every second a laser pointer emits a number of photons equal to (3.2x10 18 photons/J)(0.001J/s) = 3.2x10 15 photons/s. Now that we know how many photons are produced per second, we need to know how much momentum is carried by each photon. WebWhich is indeed `many photons'. (That could be an overestimate by a factor of about 2, depending on whether your '800 Watt' microwave is one that consumes 800 W wall plug power, or one that puts a useful 800 W into the oven. greensville county public schools
