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?
The stars are not visible during the day because bight sunlight scattered by the atmosphere masks the relatively dim light of the stars.
What wavelength is the peak output for an incandescent light bulb?
The peak output wavelength for an incandescent light bulb is typically in the infrared region, around 1000 nm. However, a significant portion of the emitted light is also in the visible spectrum, with peak emission in the red-yellow range.
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 When the leave of the deciduous trees turn in autumn you can see the colours of many of these as they are selectively withdrawn.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.
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
Why you cant see visible light?
If your vision is normal, then you CAN see visible light.
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.
What types of light humans cant see?
Ultraviolet light and infrared light are two types of light that humans cannot see. Ultraviolet light has shorter wavelengths than visible light, while infrared light has longer wavelengths. Both types of light are beyond the visible spectrum for humans but can be detected with specialized equipment.
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.
What is a material that light can't travel through?
There is no known material that light cannot travel through. However, materials such as lead and thick concrete can significantly attenuate or absorb light, making them almost opaque to visible light.
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.
When are objects visible to us?
Objects are visible to us when light from the object enters our eyes and is detected by our retinas. This light stimulates nerve impulses that are sent to the brain, where they are processed and interpreted as images. The visibility of an object also depends on factors such as its size, distance, color, and the amount of available light.
What has a single eye but cannot see?
traffic light :)
Why cant humans detect infrared light?
Humans cannot detect infrared light because our eyes are only sensitive to a limited range of wavelengths, known as visible light. Infrared light has longer wavelengths than visible light, making it undetectable to our eyes. Specialized equipment, such as infrared cameras, is needed to detect and visualize infrared light.
Why cant you use visible light to see molecules?
because light used to see an object must have a wavelength
