What are Advantages and disadvantages of using photocells to generate electricity?
The good reasons of having a photocell in a park are that it can be left alone once set up, can get energy for free (form the sun), it can store energy for long periods of time, but were there are advantages there are also disadvantages, which are it doesn't gain as much power at night or in low light conditions, its expensive to buy/ get set up. hopes it helped :)
What is the Impact of technology on security?
Technology has had a significant impact on security at all levels. With advancements that take place in technology it is possible to create security products that virtually undetectable and allow for a truer result. You can view security footage live from most mobile devices.
What technology is used to study avalanche?
your mom is used by the way I had your mom over last night it was fun
Why is infrared used in night vision technology?
Answer Most visioning systems, the unaided eye, regular cameras, and even night vision googles all rely on there being a source of light shining on whatever you wish to see, and some of that light bouncing off the object, and back into your eye. The systems usually referred to as Night vision are usually based on light amplification, and doesn't work in absolute darkness. Even the best ones needs a tiny bit of light to work with. (Passive) infra red works in a completely different way. All things that are warmer than absolute zero radiates some thermal energy - heat radiation, in the area of wavelengths called infrared. If you have a device sensitive enough to these wavelengths, you can then see your surroundings by the radiation from the temperature differences between different objects. (Passive) IR does work in total darkness, as long as there are enough temperature differences in the scene. You could bring it down into a deep cellar, or a cave, and you'd still see something. As a separate sub-set there are Active IR systems as well. These work pretty much like regular visioning systems, only with the illuminator and the viewer shifted out of the range of the unaided Eye. Answer infrared rays lie in that part of light spectrum that is invisible to human eye, however some highly sensitive light sensors detect infrared rays, so these rays are used in night vision cameras and binoculars. these rays are focussed at some object that has to be viewed. the infrared sensors detect the reflected rays from that object and this is how we can see in the dark using these rays. Answer because it enables you to see warm objects, so if, for example, somebody was lost on a hill, in the dark, you would just have to scan for a hot human shaped blob, instead of using torchlight
What technology helps to find out more about stars and planets?
Usually, the telescope, the Hubble Space telescopes are some examples or telescopes. There are ground ones and also ones that are launched into space. There are also rocket launches. They are basically, space shuttles/space ships that are launched into space to capture pictures, and used to take astronauts up there to study more about space. Star charts are another example of technology that are used to study the night sky.Scientists use it to record down the exact mark of where the stars are...not really something that is tootechnical. Satellitesare also used in these situations, too. They can take pictures, get closeups towards planets, etc.
What is the advantages of night vision?
To see in the dark
Do night vision goggles have any disadvantages?
yes
What are some advantages of night vision devices?
Because humans have poor night vision.
Who invented night vision technology?
mitchell andrew forbes
The advantages to prestige in modern warfare 2?
You get night vision goggles!
What does a telescope do to improve your vision of the night sky?
It magnifies the available (ambient) light. Night-vision technology amplifies available light by as much as 40,000 times.
Night vision technology I want to give presentation on this topic. So tell me everything about this technology.?
"Night Vision" technology is actually called light amplification technology. If it is pitch black and light is completely absent it will be pitch black in the goggles. The ratings on specific devices are different, but no matter what they all require some kind of light source.
What is the definition of night vision goggles?
Night vision goggles use special technology to amplify the tiny amounts of natural light that's usually always around into levels that our own eyes can use.
Do night vision technology exist in India?
Yes its available in India. The military uses it all the time
What would a night vision monocular be used for?
A night vision monocular is typically used for enhancing visibility and observing objects or activities in low-light or dark environments, providing clearer vision and the ability to see in the dark with the assistance of infrared technology.
What are some advantages and disadvantages of radiant?
Advantages- Radiant energy gives off heat. Radiant energy makes it visible to see in the dark at night. I cant find any did
Which vitamin causes night vision?
Vitamin A is necessary for night vision.
