Subject: Re: [Phys-l] E-M radiation pressure
I guess I must go back to reading school. Appeared clear to me:
4B50.62 radiation and convection H-165 Put a hot metal
object in a smoke filled projection cell and the smoke will be
repelled by radiation
pressure. Convection will cause an upward clearing.
Radiation repels smoke was what I questioned.
bc, thinks Michael is a bit huffy.
p.s. If it's true (Such IR radiation will repel smoke.), please
explain. BTW I couldn't find the projection cell demo. Which page?
