The double-slit experiment is a demonstration that matter and energy can display characteristics of both waves and particles, and demonstrates the fundamentally probabilistic nature of quantum mechanical phenomena.

In 1801 Thomas Young was able to offer some very strong evidence to support the wave model of light. He placed a screen that had two slits cut into it in front of a monochromatic (single color) light. The results of Young's Double Slit Experiment should be very different if light is a wave or a particle.





The wave nature of light causes the light waves passing through the two slits to interfere, producing bright and dark bands on the screen — a result that would not be expected if light consisted strictly of particles. However, on the screen, the light is always found to be absorbed as though it were composed of discrete particles or photons.

50, not counting the various territories.

What colors do dogs see in? (hint, it's not just black and white)
They also see red, probably because they have more red conical photoreceptor cells than they have blue and green (though I'm not entirely sure if they do have even just a residual amount of the latter cells). Black and white is detected by rod cells. ^^

Next Question:
Do we believe before we understand, or do we understand before we believe, or are they just a similar concept altogether?
[I can provide a link if no one can answer. :)]

How many US states are there?
I'll say 51

And (in case that's right) Who plays speech therapist Lionel Logue in the film "The King's Speech"?
