    Double slit questions from an observation perspective

    Okay, so then moving to either side through light and dark areas looking back at the slit we see it as lit or not depending on our position in the projection screen? Can we see the space between the slits or does it just appear as one slit?

    Double slit questions from an observation perspective

    Some questions have been haunting me about this experiment for some time. I'm mainly interested in what we observe from the perspective of the projection screen. First lets imagine that there is only one slit, and we are observing from the projection screen looking back at the slit with the...

    Osmoregulation in freshwater fish

    The parasites "Hexamita" are thought to always be present in the intestines. When fish are under stress, or their diet contains hard to digest proteins, the parasites can multiply create blockages, and puncture the intestine linings. They can then enter the blood stream and internal organs...

    Osmoregulation in freshwater fish

    I'm basically concerned with african cichlids, and more specifically those from lake malawi. This question stems from a debate on the Cichlid-Forum. It is widely recommended there and other places that specialize in these cichlids that adding epsom salt to the aquarium water will help flush...

    Osmoregulation in freshwater fish

    I'm interested in understanding this process (Osmoregulation) better. There is some debate about treating freshwater fish by adding medication to the water, and for some instances adding epsom salt. I have read that osmoregulation in fish only allows water to pass through the skin, and not...

    Why didn't the big bang just become a black hole?

    My understanding is elementary at best, but I think analogies relating to the size of the universe at any point in time can only refer to the observable universe of a location. Two marbles may be only be separated by a small distance, but each marble's center has its own observable universe...

    Bike gear ratio

    I think you just divide the number of teeth on the front sprocket by the teeth on the back, e.g., 100 front 10 back = 10 to 1

    3D or 2D image in a Mirror

    Part of it is the fact that a mirror reflection is flipped compared to a picture. Hold up your right hand in a mirror and in a picture, in the mirror it looks as if your left hand is up.

    Why does the photon bounce vertically in the light-clock?

    I'm no expert certainly, but it's my understanding that an accelerating light clock will not count seconds properly in its own frame. The photons will travel at an angle away from the direction of acceleration causing the photon to either miss the reflector (if the reflector was small enough) or...

    Rotating a laser beam faster than light?

    While I understand part of your point, your explanation is flawed. Using the example of the target being one light year away, if the laser starts to rotate yes it will take one year to notice this on the receiving end. At that point though the spot will start to appear to move faster than the...

    Is black a colour?

    What happens to light when it hits an oxygen atom? Does it just go right through as if the oxygen atom isn't even there, with no interaction at all? Is there no chance that the light is absorbed by the atom, then is emmited as a wavelength outside the visible spectrum? If the second question...

    Is black a colour?

    This arguement falls into line with the comment I made about turning my head away from the paper. It was dismissed quickly, and rightfully so. If an object is truly black you can't see it even when the lights are on...

    Is black a colour?

    Why do you keep asking the same question, I already answered it. You want to talk about 0 kelvin, fine. Something that absorbs all visible light obviously doesn't reflect any... Something at 0 kelvin obviously doesn't emit any light... Do you still need to know where I got the definition of...

    Is black a colour?

    It's not a definition, I'm simply relating conditions of matter that fit it into the definition of black. If you have something else to offer I'm all ears. If someone here doesn't agree that by definition oxygen, and other colorless gases fit into the definition of black, then I would like an...
