a big Q

KIRTI KUMAR wish
a big question?
Acc. to einstein's equation m=m0/sqrt(1-(v^2/c^2))
for a photon v=c;
therefore,m=infinity;
hence its momentum is huge...
but it does not have any impact why??

akshay answered:Akshay
no m is not infinity
for photon m0=0,0/0 is not infinity
mc^2=hc/lamda
so mc=h/lambda
so momentum of photon=h/lambda

but, acc to me,

its a very small Q.
photons r not particles, and so, it doesnt have mass............the rest of the following Qs r then useless to b answered........

m i correct?????

see Q here....http://www.orkut.co.in/Main#CommMsgs.aspx?cmm=47023448&tid=5277108815011099257&na=4

Actually rest mass of photon is zero!

Also there is this dual nature of particles.

yesterday sky gave me a link to an awesome video explaininng dual nature of light.. initially it gives a part on interferece

try to see the full video..
