dark.

you do and can not deny that in daytime hours you can see through light, but you are not seeing through light, you are seeing through the dark, emr makes the dark ''transparent'' it is undeniable.

 

Light (or emr if you wish) does not have any effect on "darkness". If you go onto a hign mountain at night time where the air is clear and shine a torch up into the sky, it has no effect on the darkness above you. If you used a very powerful light source, such as a laser, you might see the laser beam. But that is simply because the light scattered from the air molecules is sufficiently intense to be visible.

Can you add this post to "dark".. I was in middle of writing when you locked it..

And what exactly would you suggest in a way to measure something that can have no maths?

What have no math?

Photons causes increase of temperature of matter they hit and are absorbed. You feel it every day on your skin..

So, take light bulb, put it a few centimeters from container with water. Measure initial temperature of water. Then leave it for minutes or hours (measure time). Measure temperature again. Now you see increase of temperature caused by light in visible spectrum + IR.
Then you can take new water, place polarization filter between light bulb, and repeat experiment. Now you have temperature of water caused by photons filtered by polarization filter.
You can place a few polarization filters in group. With different angles of rotation.
You can place color filters.
Place red filter, see effect caused by just red photons.
Place green filter, see effect caused by just green photons.
Place blue filter, see effect caused by just blue photons.
You know how much energy light bulb used from ampere meter and voltmeter.
You know time from stopper how long it took to increase temperature.
You know temperature increase from thermometer..
