If that's 449 millimeters, centimeters, meters, kilometers, inches, yards, or miles,
then no, your eyes don't detect it.
If you mean an electromagnetic wave with wavelength of 449 nanometers, then your
eye would react to that, and would interpret it as the presence of violet-colored light.
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
Infrared has a longer wavelength, and a lower frequency, than visible light.
The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.
"UV" (ultra-violet) is radiation with shorter wavelength/higher frequency than visible. Infrared is radiation with longer wavelength/lower frequency than visible.
blueee!!
No, frequency and wavelength of visible light are directly related through the speed of light in a vacuum. The frequency of visible light waves is inversely proportional to their wavelength: shorter wavelengths have higher frequencies and vice versa. This relationship is described by the equation c = λν, where c is the speed of light, λ is wavelength, and ν is frequency.
The highest frequency (shortest wavelength) of visible lightis the light at the blue end of the visible spectrum.
Violet has the shortest wavelength and highest frequency among visible light colors, whereas red has the longest wavelength and lowest frequency.
No. In the visible portion of the electromagnetic spectrum, the waves at the red end have the longest wavelength (lowest frequency), and those at the violet end have the shortest wavelength (highest frequency).
No, red is the longest wavelength of visible light, with the lowest frequency and the least energy. Violet light has the shortest wavelenght, with the highest frequency and the most energy (of visible light).
As far as visible light is concerned violet has highest frequency and shortest wavelength where as red has lowest frequency and so longest wavelength VIBGYOR is the order of colours in the visible spectrum
Visible light. The higher the frequency, the shorter the wavelength.
