What is the wavelength of blue light if it has a frequency of 6.67 x 1014 sec Hz?

Answer 1

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

Answer 2

The frequency f = 667,000,000,000 Hz of blue light equals the wavelength lambda = 0.000000449 meters = 449 nanometers. Scroll down to related links and look at "Radio and light waves in a vacuum".

Answer 3

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".

Answer 4

The color of the wavelength lambda = 446 nanometers equals the frequency f = 672,180,399,103,139 Hz (blue light). 1 nanometer = 1×10−9 meter 446 nm = 0.000000446 meters Scroll down to related links and look at "Radio and light waves in a vacuum".

Answer 5

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

Answer 6

=6.70×1014

Answer 7

The wavelength is λ = c / f = 299,792,458 m/s / 6.67×10^14 Hz

= 4.4964 × 10^−7 m.

Answer 8

Please use the standard formula for waves: speed = frequency x wavelength. Convert the wavelength from nm to meters; the speed of light is about 300,000,000 meters/second.

Answer 9

Frequency = speed/wavelength = 299,792,458/670 x 10-9 = 4.4745 x 1014 Hz = 447,450 GHz
