Blocked holes can enhance rather than stop light transmission

Oh noes its too late for you the government seems to have cloned you already!!!

They can have my tin foil hat when they pry it out of my cold dead hands!

You wear your tinfoil cap on your hands? How odd.

No. OddER. ;-)

"Light" continues to baffle scientists.
It's both a wave and a particle (something can't really be both).
It seems to be able to exceed its own max. speed limit.
And then there's Quantum Mechanics - or maybe there isn't.
What about "gravity" - what is it and what is its origin?
"Science" is certain there is no God, but really isn't certain of much else....

I wear a colander. I'll try blocking the holes to see if more light comes through.

Take the spaghetti out first.

[MIchaelTArchangel]

Gee, and my wife thought it was crazy that when I was constipated she could shine a light into my left ear and the beam came out my right ear. That effect when away after I became “unplugged”.

[frithguild]

Yes, blocked holes mays things lighter

[Mr. K]

with two holes you get interference patterns where half the light will cancel out

block one of them and you get the whole of the light coming through one hole, I have noticed this before too- it seems brighter

“”Light” continues to baffle scientists.
It’s both a wave and a particle (something can’t really be both).
It seems to be able to exceed its own max. speed limit.

I have an atheist brother-in-law. Another is agnostic. They are incessantly quoting “science” (i.e., popular sci-fi) to support their positions. The atheist has a doctorate in mathematics. I love asking him, “So, explain to me again why gravity is so weak?” Light should be simple for a species that has the whole universe figured out.

[Secret Agent Man]

If you need new questions ask him these:

1. Explain why all planets do not rotate the same way, but some rotate the opposite?

2. Explain why Jupiter has moons that orbit in opposite directions?

3. As gas dissipates in the vacuum of space, explain why the gas giants have not dissipated?

4. Why do some planets have rings and others do not? After “billions of years”?

5. If cosmic evolution is true (big bang, out of smaller elements galaxies, stars and planets form out of these elements), that means from an explosion (disorder) came order (the universe) - yet this is the exact opposite of what we observe in the universe - namely the 2nd Law of Thermodynamics, that states over time order degrades into disorder. How do you explain that the theory of cosmic evolution violates the 2nd Law of thermodynamics?

An interference effect is not what's going on here. They're getting 70% better light transmission with all of the holes blocked. The electric field component of the light is coupled to a surface plasmon in the blocking disk which propagates around the surface of the disk and releases it on the other side. The idea is that the [conductive] blocking disk is acting as an antenna.

Works with light shining from either side, too (which it wouldn't if it were a refractive or diffractive effect).

Hey Chou! If the light’s gettin’ through, the hole’s not blocked.
