in response to Cyparagon: I agree Q=CmΔT is a better/easier equation to use:thanks:. In response to anselm: I was thinking more about how much energy is carried in the laser beam. Then i can build on this to calculate absorption in different materials, conductance and energy densities ( affect...

Hi guys I'm new to this, but i've seen alot of post relating to the power of lasers and think a good way to visualize it is heating power ie temperature increase of water in 1 second. I know C=Q/ΔT where C =Specific heat, Q =heat and T =temperature and dimensionless heat capacity = C / Nk...

i'm planning to use a 5mw red laser for some light experiments, diffraction patterns etc, could you confirm that light reflected from a white screen won't damage eyes. if not what goggles would you recommend for this type of thing. cheers
