Is 400 nm light visible?
Light from 400–700 nanometers (nm) is called visible light, or the visible spectrum because humans can see it. Light outside of this range may be visible to other organisms but cannot be perceived by the human eye.
What color has a wavelength of 450 nm?
The visible spectrum
| colour* | wavelength (nm) | frequency (1014 Hz) |
|---|---|---|
| yellow | 580 | 5.16 |
| green | 550 | 5.45 |
| cyan | 500 | 5.99 |
| blue | 450 | 6.66 |
What color is a 480 nm on the visible spectrum?

Color Physics
| Color | Wavelength (nm) |
|---|---|
| Yellow | 550 – 580 |
| Green | 490 – 530 |
| Blue | 460 – 480 |
| Indigo | 440 – 450 |
What visible light having a wavelength that is about 475 nanometer?
visible blue light
The visible blue light has a wavelength of about 475 nm. Because the blue wavelengths are shorter in the visible spectrum, they are scattered more efficiently by the molecules in the atmosphere.
When wavelength is 490 nm which Colour is absorbed?
blue-green colour
The wavelength region 490-500 nm corresponds to blue-green colour. Its complementary colour is red.
Is 400nm a UV?
UV-A light (320-400nm) is UV light with the longest wavelength, and the least harmful. It is more commonly known as “black light”, and many use its ability to cause objects to emit fluorescence (a colored glowing effect) in artistic and celebratory designs.
What color absorbs at 400 nm?
Complementary Colors If wavelengths of light from a certain region of the spectrum are absorbed by a material, then the materials will appear to be the complementary color Thus, for instance, if violet light with wavelength of 400nm is absorbed, the material will look yellow.
What color has the longest wavelength?
Red has the longest wavelength among the given options.
What would the frequency of light at 470 nm be?
To find the actual value of frequency with Hertz (Hz) unit, we should convert this value from nanometre (nm) to metre (m) & then apply the formula equation of finding the value of frequency which is____ frequency = Velocity of light/wavelength. Therefore, the frequency of blue light is 6.52173913×10^14 Hz that has a wavelength of 460nm.
