If you place your TV remote in front of your digital camera you will be able to see light,why are we able t?

wow, i just did it and it's really cool!

Good point! \nCongratulations, that's got me thinking. Ouch!\n\nCould it have something to do with maintaining the frozen goods in the freezer, which obviously is less important in a fridge. Afterall, when the light comes on in the fridge it produces kinetic energy that turns the light into heat which could linger trapped inside once the door is shut again. \n\nWell, that's my feeble attempt at an answer. It would just drive me crazy otherwise!

I am guessing you are asking a more basic question.  Light spreads out as it propogates making stuff that is far away appear dimmer.  Understanding the distance to something is therefore necessary to understand the total power production of a source. If light did not spread out, this would not be an issue in research. \n\nThe apparent brightness falls off by a factor of 1/d^2 where d is the distance between the observer and an unresolved ("point") source.

Never noticed that. Maybe I should pay more attention to my tv.

Use the night mode on your camera. Or rent a light kit.

So they can get the TV camera behind it.\n\nIn the real world they don't.

You would need to do a double blind test, for Controlled Remote Viewing. called CRV.\n\nYou can learn from several sources on DVD or take an in person course. Check out the RV website.

I am willing to bet (but am not completely sure) that the LED pulses, which can be interpreted digitally, to perform the different actions (how else would the TV "know" to adjust volume, channel, ect?). The universal remotes would simply have all those different coding systems preprogrammed into it (notice how you have to select one with a universal remote). You could probably figure it out for sure by probing the input trace to the LED with an oscilliscope and enter in various commands, but who has the time right?

Sometimes that has to do with the amount of "black" there is or isn't on the screen.  Setting the contrast up all the way has a similar effect.  Try going into the menu on your tv and set all the settings to the middle or if possible on "default".

At the moment there is a flash, the flash is a light source. Not the camera itself.\n\nTh

That could get extremely detailed, but here is a simplified explanation that can fit here.\nThe TV screen is a collection of little pixels, one besides the other, arranged in lines.  The camera that takes the picture that is to be shown on TV grabs the image and then evaluates the color in each pixel of each line, and each lines, and sends that information as a signal.  The TV receptor receiving that signal (that could have been encoded, sent by cable or through radio waves, etc) then gets a signal that essentially says "first line" followed by the description of each pixels.  Then it sends the third line (the even lines are sent after the odd ones, this is what is called interlacing) and the 5th and so on until the end of the half picture.  The electronics in the TV use the signal to project a beam of electron of variable intensity to a target that is made of fluorescent phosphor, that light up as a result, and you see the picture from the other side.  Evidently, if your TV is a LCD or a plasma unit, the technology to actually reproduce the image varies from the old cathodic tube method, but the result is the same, you get an image.

A common garden variety TV screen is a Cathode Ray Tube- the screen itself is a phosphor coated glass surface attached to the vacuum bottle and electron gun assembly that makes up the rest of it. In operation the electrons from the gun at the rear of the thing are electromagnetically accelerated to the phosphor screen, and scanned by electromagnetic deflection back and forth over the phosphor, making little dots of light that cumulatively make the "picture"- each dot is a "picture element" or pixel the whole accumulation makes a recognizable image. and if you like I can explain how the thing work in color, too.

That is probably a dead pixel. This could make it worse or it could fix it, Push on the spot, Then turn on the tv. Try at your own risk! It worked for me.

What type of computer?\n\nRemote to do what?\n\nThere are remotes for certain things like T.V/video cards and a few other things but depending on what you want it for ther may not be a remote.

Most microscopes have lighting underneath the slide tray.  If the slide were opaque, not clear, you would not get sufficient lighting up through the slide and into the optics.

It has nothing to do with the speed of sound or the speed of light.  Until the sound or picture actually leave the TV, both signals move at the speed of electricity.  The exact speed depends on the electrical components making up your electronic circuit, so the two signals may be moving at different speeds.  Regardless, both signals move through their respective circuit fast enough you would never be able to perceive the difference.\n\nThe reason for the delay is that the picture tube is a cathode ray tube.  It uses an electron gun, which shoots electrons at the screen on the front of the TV.  The way it shoots these electrons is to heat up the cathode until electrons are released.  The electrons are sped up in the general direction of the screen by electrodes at the other end of the gun and aimed at the appropriate spot on the TV by electromagnetic fields.  \n\nThe delay in the picture is because of the time required for the cathode to get hot enough to begin emitting electrons.\n\nEdit:  If the idea of an electron gun shooting electrons at the front of the screen makes you nervous, you're not alone.  In the early days of TV, lots of moms persistently told their kids not to sit so close to the TV for fear of damaging their kids' eyes.  Actually, the electrons never pass through the phosphorent screen.  The main hazard associated with color TVs are related to the small amount of X-rays emitted when fast moving electrons hit the screen (black and white TVs don't shoot electrons fast enough to produce X-rays).  These are blocked by leaded glass, but the leaded glass itself is toxic should you somehow break your picture tube.  The leaded glass is also one of the reasons disposing of old TVs and computer monitors in landfills are a bad idea.

This is how films are recorded, they all are made this way and then modified to fit youir screen, but more commonly you will see less and less modification and anything less than high a def TV will be obsolete.  Sooner or later even all cable will be broadcasted this way and without a high def TV you will see the annoying black bars accross the screen. I hope this anwers your question
