Why are UV rays invisible?
UV rays are part of electromagnetic spectrum just like light. Some rays can be detected by the eye and some cant. The sunlight we see is the visible part of this spectrum that is why it is called visible light. Initially only light would reach the earth but now because of ozone depletion even UV rays reach the earth. So basically they are invisible because they are not part of visible light.
Why cant we see stars during the day?
We can, t see the stars in a day beacues the light of sun is very bright comparatively to the stars thes reason
What is the electromagnetic spectrum Which part of the electromagnetic spectrum do plants use for photosynthesis?
Primarily Yellow but really it uses most of the visible spectrum, just some parts more than others. Green plants actually have five type of pigments that serve in photosynthesis. When the leave of the deciduous trees turn in autumn you can see the colours of many of these as they are selectively withdrawn.
What is the list regions of electromagnetic radiation in the order of wavelenghts from the lowest to the highest?
The regions of the electromagnetic spectrum for short to long wavelengths are: Gamma rays -> X-rays -> Ultraviolet -> visible -> Infra Red -> microwaves -> radio waves.
Does light produce both electric and magnetic field?
light exhibit magnetic field but i cant say about electric Field...
Why you cant see visible light?
If your vision is normal, then you CAN see visible light.
How can you make a compass needle face the wrong way?
you cant really because the magnet in the compass controls and direct it the way it needs to go
When are objects visible to us?
we see things when a light source goes into our eyes or when it reflects off an object
Why can radio telescope can see things that a telescope that detect visible light cant?
-- The source may be one that emits electromagnetic energy in the radio portion of the spectrum but little or no visible light. -- There may be material in the way, such as dust or gas, that absorbs visible light but doesn't absorb radio energy.
Why cant we live without visible light?
We cannot live without visible light because in our homes, we would keep bumping into things and injuring ourselves, and when we went outside, we would be greatly inconvenienced by the increased number of traffic accidents.
Why is it that you can feel the blow dryers hot air but cant see it?
Air does not absorb or reflect enough light to be visible, regardless of what temperature it is.
How cant he magnet show the presence of a magnetic force?
by simple moving of its needle,or by change the direction of needle.
Why cant you see visible light to see molecules?
In order to "see" something with eyes, the object must be longer than the light wave refracted from it. Molecules are too small to be refracted.

How can you see the UV light in laminar air flow otherwise usually you cant see the uv ray?
UV bulbs usually have a coating on the inside that glows when the light is on, providing indication in the visible light part of the spectrum.
What would happen if the compass was never invented?
If compass was not invented we would get lost and cant find ourselves. That's way in TV you see people using compass in the desert.
What has a single eye but cannot see?
traffic light :)
