Warning: This is a potentially stupid question! Is it possible to induce photosynthesis with laser light? What kind of published work is there on it? Thanks!

I expected the demographic to be younger here, that's why I made smaller categories, but 16-21 being the predominate age is still a surprise.

That's interesting, I did not know that. What book/text would you recommend for me to understand photon behavior more completely? Yes! Problem solved!

Slaughterhouse-Five was awesome.

I'm curious about demographics here at the Physics Forum.

So EM waves have their own set of laws that have nothing to do with classical physics right?

btw, I want to preface this with "I don't know" I'm just trying to figure this out. That makes sense that it would not need a continual force to maintain it's velocity, but what initially forced the wave to that velocity? Because light shows signs of particle-wave duality, wouldn't the...

I would agree that you are exerting a force, because you are accelerating the ball at 9.8m/s^2 in the opposite direction from the center of the gravitational field. However mathematically, Work is defined by Force x Displacement, there is no displacement. So no work is being done.

I've been thinking about some really elementary ideas of light and I just can't get a handle on this. Everything on the electromagnetic spectrum travels at 3.0 x 10^8 m/s, but what force is exerted on these waves to travel at this speed and wouldn't Newton's third law mean that there would...
