What else can I help you with?
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 kind of radiation can we feel but cant see?
We can feel infrared radiation as heat, but we can't see it with our eyes because it's not within the visible spectrum. This type of radiation is often emitted by warm objects or the sun.
Why you cant see visible light?
If your vision is normal, then you CAN see visible light.
What do you call a band of colors when light passes through a prism?
There are more than seven but only seven are visible. They are red, orange, yellow, green, blue, indigo, violet, and the one that cant be seen is ultra-violet.
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 When the leave of the deciduous trees turn in autumn you can see the colours of many of these as they are selectively withdrawn.
Which part of the electro magnetic spectrum allows us to see?
The visible light portion of the electromagnetic spectrum allows us to see. This portion of the spectrum ranges from about 400 to 700 nanometers in wavelength, with colors ranging from violet to red. Our eyes are sensitive to this range of wavelengths, allowing us to perceive light and colors in our environment.
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.
Is all matter visible?
no. all matter cant be seen. like air is a matter but we cant see it.
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.
What if the jugular vein is visible while lying flat?
It cant be visible because it is hidden behind your throat.
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.
Why cant light of 500 nm be given off from hydrogen?
Hydrogen, like all elements, have a characteristic distance between energy levels. The atom can only accept photons of energy that match that distance and then that light is emitted. 500 nm does not match the wavelength of light that matches the wavelength corresponding to the energy gap in hydrogen.
