does air reflect better when there isn't humidity?

Reflectivity depends on the index of refraction, so it depends on what happens to the index as humidity varies.

 

So...the light will reflect or not?

Air doesn't normally reflect light.

noone, perhaps you could explain what you mean.

 

Also, it's easier if you ask one question in each thread.

 

I just wanna find a way to reflect in the air and i m traino to get more information possibile about it

If you had two layers of air with different densities (perhaps owing to a temperare difference) younwould get reflection. A tiny, tiny amount, at the interface. Refraction is much more common, since that doesn't require a sharp change in index.

That is a strange definition of reflection. Why can't we see it?

beacause the waves of the light are too smaller to be seen by human eyes.

so the humidity isn't a matter?

What do you mean by "too small"? Wavelength? That would not be changed by reflection.

2-Some organism can see smaller waves of light then us... can i now which organism can do it?

 

This is more of a biology question.

3-how does projector works?

 

I think that needs a separate thread.
