Blue light has a wavelength of 450-495 nm (nanometers or billionths of a meter). It falls in the higher frequency of the visible light spectrum.
Red has the longest wavelength (620-750 nm) and violet has the smallest wavelength in the visible spectrum. The human eye can perceive wavelengths ranging between 380 (violet) and 750 nm (red). Blue has the second shortest wavelength after violet.
These are the wavelength ranges for each of the seven colors that comprise the visible spectrum:
(Color) (Wavelength)
violet 380-450 nm
blue 450-495 nm
green 495-570 nm
yellow 570-590 nm
orange 590-620 nm
red 620-750 nm
The wavelength of light can be calculated using the equation, λ = c / f, where c is the speed of light (approximately 3.00 x 10^8 m/s) and f is the frequency of light. Plugging in the values, the wavelength of blue light with a frequency of 6.67 x 10^14 Hz is approximately 4.50 x 10^-7 meters or 450 nanometers.
The color of the wavelength lambda = 685 nanometers is "deep red" and not blue. The wavelength lambda = 685 nanometers equals the frequency f = 503,852,870,588,235 Hz. Blue light is between 490 and 450 nonometers. 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".
For any freq / wavelength combination, their product always equals the speed of light, c,
e.g. freq * wavelength = 3 x10^8 m/s
This is handy because given any freq or any wavelength we can always compute the missing value because the speed of light is constant.
So, in your case 6.26 x 10^14 Hz (freq) * wavelength = 3 x 10^ 8 m/s or, rearranging:
wavelength = (3 x 10^8 m/s) / 6.26 x 10^14 Hz
wavelength = 4.79 x 10-7 m
similarly, if given a wavelength and asked for a freq, you divide c by the wavelength
Hope this helps,

The wavelength of blue light with a frequency of 6.82x1014 Hertz is approximately 440 nanometers. This is calculated using the formula: wavelength = speed of light / frequency.
To calculate the wavelength of the blue light emitted by the mercury lamp, use the formula: wavelength = speed of light / frequency. The speed of light is approximately 3.00 x 10^8 m/s. Convert Hz to s^-1 by dividing by 1/s. Then, plug the values into the formula to find the wavelength in meters, which can be converted to nanometers by multiplying by 10^9.
Red has a lower frequency than blue. Blue light has a higher frequency and shorter wavelength compared to red light.
No, red waves have a longer wavelength than blue waves in the light spectrum. Blue light has a shorter wavelength and higher frequency than red light.
The frequency of blue light with a wavelength of 451 nm is approximately 666 THz (terahertz). This can be calculated using the formula: frequency = speed of light / wavelength. In this case, the speed of light is approximately 3.00 x 10^8 m/s.

Red light has a longer wavelength and lower frequency compared to blue light. Blue light has a shorter wavelength and higher frequency, which is why it appears bluer in color to the human eye.

The color, the frequency, and the wavelength.
The frequency of blue light with a wavelength of 451 nm is approximately 666 THz (terahertz). This can be calculated using the formula: frequency = speed of light / wavelength. In this case, the speed of light is approximately 3.00 x 10^8 m/s.
The colors in order of increasing wavelength are violet, blue, green, yellow, orange, and red. This sequence follows the visible light spectrum where violet has the shortest wavelength and red has the longest wavelength.
Red light has a longer wavelength than blue light, (i.e. greater distance for one oscillation of red light compared to blue light) so there are less oscillations in the same period of time for red light, and thus red light has a lower frequency than blue light. More concisely: Wavelength = Wavespeed / Frequency , where wavespeed is constant So Frequency = Wavespeed / Wavelength Therefore as wavelength increases, frequency decreases. Make sense? Jack
No, yellow light has less energy than green light. Green light has a higher frequency and shorter wavelength, which corresponds to higher energy. Yellow light has a longer wavelength and lower energy.
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.
