Iridescence

[Damien]

What object clear or opaque are best for absorbing and irradiating light from its surface. In other words, if I point a light at it, can the light be seen reflecting off the surface at its surface; like a mirage.

If you are not talking about laser light, then this is the wrong place to post this.

I'm assuming you're in Greenland waking in the twilight.

I think you are talking about Ulexite (TV-rock),

But, I don't really understand the question. :thinking:

The "General" section is for laser related questions. This question should have been posted in the "Other" section.

Interesting... Does the light enter the rock and cast itself on the other side? Ergo, a sculpture of this material and lasers hitting its base; the light would dissipate within or on its surface.

Sorry. I still don't get what you are asking. But, I'll try. :yabbem:
1. The light (laser light for instance) enters the rock on one side, and looks like a laser "dot" on the other side of the rock, but the light cast "against the wall" is in a concentric circle pattern (see first image).
2. Well, I am pretty sure the light won't dissipate within at all due to the properties of Ulexite (similar to fiber-optics). The light would just pass through the material (as seen in the image with the green laser above) and dissipate (scatter) after exiting the Ulexite crystal. :tinfoil:

Yes, such a concentration of light [laser]. I'm talking about mirroring it off a surface and creating a mirage effect over the lasered surface.

Are you able to clarify what you mean my "mirage"

Still confusing me when you say that.

There are reflective diffraction gratings, you point a laser at a tile like object, and the reflected beam is diffracted into an array.

 

[Damien]

It is confusing, but is it plausible to refract the light of a laser only so far from a reflective surface?
In truth, the glare from that surface could give the optical effect of a laser splash rising several inches above it.

The light has to "hit" something (dust, steam, haze, etc.) in the air to be seen. Plus, it will not "stop" just a few inches above the surface, unless you stop it with something.

I'm inclined to agree.
