Re: QUANTA



Sarma,
No, this explanation is OK, because I am not saying that the
radiation from the point of origin is particle or wave. It is true that
most, if not all, E&M text that tackle radiation will say that it is a
wave. However, all radiation can also be particle. For interference
effects, one can account for it by the wave nature of matter, i.e.
deBroglie waves. It is ture that the oscillating E&B field give a
better explanation of the wave nature, but don't forget that the photon
is the mediator of the electromagnetic force and deals with the
interactions of the E&B fields. This matter is too complex to get into
with high school students and even most undergraduates. Even I cannot
put into words what I know and feel. Sorry, I hope this response is
adequate.

The light is just
oscillating E and B fields and appear as such until measured.

Can we say this? Is not this also one of the two results of measurement?

Subject: QUANTA


A student asked if one could talk about quanta if an antenna was
broadcasting a frequency in the blue range of the visible spectrum for
example. Would we see it as blue? Would the mechanism for seeing it be
any different from seeing quantized forms of blue light?

I hope my question makes sense but it seems there is a difference here
but I am not sure how to explain it.

Thanks for any help, David Abineri
