Hello,
If light contains a certain (particle/wave) duality, then is it possible for photons to not have a constant velocity? In short, can light slow down in particular cases?

Two canoes are 5m apart on a lake. Each bobs up and down with a period of 2.0 seconds. When one canoe is at its highest point, the other canoe is astits lowest point. Both canoes are always within a single cycle of the waves. Determine the speed of the waves. (Hint: Draw a sketch!!!)

In magnetohydrodynamic (MHD) power generation, we use liquid metals and gaseous conductors. If the conditions are taken below critical, is it not a good option to use superconductors for that purpose? And what is the scope for semiconductor usage (with proper doping)?

Well we know that e.m. radiation induces currents in conductors. Take for example microwave radiation.If it is traveling through a hollow metal waveguide, in the waveguide's walls there will be high frequency induced currents affected by the skin effect.Does light have the same effect?If it does why is it so small compared to other frequencies of the e.m. spectrum? I have an idea but I will keep it to myself right now. Thank You!
