Night vision is possible with the help of?
A flashlight. Not to be a smart aleck, but you need a source of light to make night vision possible. That's technical nightvision.I assume you mean military 'I can see you, but you can't see me' nightvision.Basically, you create a headset (like binoculars that attach to your head) with two things; a special flashlight and a special camera.The flashlight emits a light frequency that we can't normally see, but the special camera can. The special camera is connect to a screen of somesort in the headset. When you put on the headset you look at the screen, so you see what the camera sees.I believe military headset used to use infrared light.A2. The Moon helps out on occasion.

How do I keep window blinds clean?
First dust off any current dust from your window blinds using a feather duster, but if you don't have a feather duster, you can also use a soft cloth to remove dust. Also, if you notice that the blinds are soiled, use a moistened cloth or antibacterial wipe to remove the soiled spots. Finally rub a dryer sheet on the blinds. This will HELP keep dust from collecting, it won't totally stop the dust from eventually collecting on the blinds, but it will slow down the process.
How can light be used to communicate?

If radio waves cannot be reflected from the Sun then how can radar be used to find the distance from the Earth to the Sun?
Yes, we don't use radar to measure the distance to the Sun directly. However, we can use radar to measure the distance to objects like the Moon and Venus, which will reflect radar. We can measure the Venus to Earth distance when Venus is between us and the Sun (more or less). Then we can simply use Kepler's 3rd Law to derive the Earth to Sun distance. Alternatively, trigonometry can be used, once the Earth Venus distance is known. We can use the occasions when the Earth-Venus-Sun angle is 90 degrees. See "related links" below for details of this. We can also use times when the Earth-Sun-Venus angle is 90 degrees. It's not that radio waves wouldn't be reflected by the Sun; but the Sun _GENERATES_ so much radio energy that any reflection would be entirely swamped by the primary signal. Think about it this way. You're in a dark theater, and people are wandering around carrying mirrors. You have a bright flashlight. Will you be able to see the reflection from the mirrors? Probably yes. Now somebody with one of the mirrors turns on a spotlight and points it at you. Can you bounce your flashlight off of his mirror ? Sure, but you can never see it. You're blinded by his spotlight, and the wimpy reflection of your flashlight from his mirror is invisible in the glare.
