Is light grainy?

[snackster17]

Ive read a few things about light and have a curiosity. If i had a single beam of light and somehow were able to zoom in close enough on this beam would i see individual photons? or would i see a stream of energy? Thank You

yes it's grainy,

in the QED lectures Feynman said that light is like rain

if you get a very very weak source of light, then you can record a single photon of light at a time, for example

thank you for the reply. Does this not all go back to the wave-particle duality though? because i read that light is also a wave frequency? perhaps the term photons and light are a bit unclear?
