How do you explain intensity of light using waves?

Is my brain miniscule, or wouldn't that just be the prevalence of light photons? Thus related to lux, rather than the waves themselves.

intensity, ie how bright it is, is the amplitude

No, unless you have a rigorous definition for the word "bright".
There are invisible IR lasers that can blind you without you ever seeing anyrhing.

according the the photon energy law E=hf the only thing that determines the energy of a photon which is the same as a EMwave is frequency, there is no amplitude and brighter light just means more waves

yes and my definition is the one in any in undergrad physics course about interference. You shouldn't have skipped classes Jamal.

That's in QED only

are you implying QED is wrong? this is all empirically and experimentally demonstrated data. when you are talking about wfew waves and its energy then it's QED, there is nothing else

Brainlet here so sorry for my retard posting, but waves always made more sense to me as spirals than a line. Thinking in terms of a spring if you look at it from a side and if you spin it that it gives the impression of movement and fluctuation

big waves are slow and soft because they’re big

small waves are fast and hard cuz they’re small

Can you visualize that as dropping multiple stones into water and looking at the water waves?

Can light energy ever cancel each other out like water waves do? What about coloured rays..

This. Timescale of measuring devices doesn’t compare to one period of EM wave oscillation. You’re finding an average value. Read Griffiths Electrodynamics Ch. 8-9 for more details.

Water waves cancel each other at multiple points at all times. If light does that, shouldn't every light source flicker when moving?
