The wavelength of visible light is approximately between 400 and 700 nm; if you divide the speed of light by that value, you will get the corresponding frequencies.
Ultraviolet light has a wavelength below 400 nanometers, infrared;s wavelength is less than 700 nanometers or so. Frequency is inversely proportional to wavelength, so ultraviolet light has a much a much higher frequency than infrared.
the wavelength of red light i.e. 700 nm is reflected from red shirt. this follows the fact that a body absorbs those light radiations which it does not contain and reflects the ones it contains. eg. the red t shirt would absorb a green or a blue radiation but when red light falls on it, it gets reflected.
The difference is the wavelength's of the two colors, Red is on the "right" end of the visible light spectrum and thus "bigger" wavelength about 640-700 nanometers while Green is more on the "left" side at around 500 nanometers.
If you mean, "which wavelengths of light can the human eye detect," the human eye can see wavelengths from about 390 to 700 nanometers.
Just ONE property, the wavelength of the light. The colour of visible light depends on its wavelength. These wavelengths range from 700 nm at the red end of the spectrum to 400 nm at the violet end.
The wave length of visible light ranges from 400 nm to 700 nm
The wavelength of visible light is approximately between 400 and 700 nm; if you divide the speed of light by that value, you will get the corresponding frequencies.
There are many possible formulas. The simplest would be to map the hearing range directly to the visible. The speed of sound in air is about 300 meters per second and the speed of light is about 3e8 meters per second. We can hear frequencies of 20 to 20,000 Hz, and that corresponds to wavelengths of 15 down to .015 meters. We can see wavelengths from 700 nanometers down to 400 nanometers. So a straight formula would be light wave length = 20e-9 * (sound wave length) + 399.7e-9 (in meters) sound wave length = 300 / (sound frequency in Hz) (in meters) Another way would be to compress the sound into octaves and let that be a linear mapping. This would be like assigning the keys on a piano to specific colors. A formula for that might be light wave length = 100 * (Log (sound wave length)) + 582.4 (in nanometers) (and I used the same formula for sound wave length above).
Any wavelength of light can be used. Natural light, the white light we receive from the Sun, is a mixture of waves with wavelengths between about 350 and 700 nm.
700 nanometers to 1 mm
700 nanometers to 1 mm
Their wave length is long, since you can see it, that means that the waves will move slower and have a longer length.
"Wave speed" is meaningless. Do you mean wavelength? That's roughly 400-700 nm.
What we call "radio" is a band of wavelengths to which the human eye isn't sensitive.-- The shortest radio wave (300 GHz) is 1 millimeter (0.001 meter) long.-- The longest visible light wave (red) is about 700 nanometers (0.0000007 meter) long.
Electromagnetic radiation travels at the speed of light, so it would make the journey in 700 years.
The color of the wavelength lambda = 685 nanometers is "deep red". The wavelength lambda = 685 nanometers equals the frequency f = 503,852,870,588,235 Hz. 1 nanometer = 1×10−9 meter. 685 nm = 0.000000685 meters. Scroll down to related links and look at "Radio and light waves in a vacuum".
