What is the wavelength of a light of frequency 6.42 1014 Hz?

Answer 1

457 nm

Answer 2

Apex - 467 nm

Answer 3

6.88 x 1014 Hz = 688,000,000,000,000 Hz c = 299792458 m/s Wavelength lambda = c / f = 299792458 / 688000000000000 = 4.3574485174418604651162790697674e-7 meters. 0.00000043574485 meters = 435 nanometers.

Answer 4

For any electromagnetic wave, the frequency (f) times the wavelength (λ) equals the speed of light (c). The unit for frequency, the Hertz, means per second or /s.

Known:

frequency = 6.67 x 1014/s

c = 3.00 x 108m/s

Equation:

c = λf

Solve for wavelength (λ):

λ = c/f = (3.00 x 108m/s)/(6.67 x 1014/s) = 4.50 x 10-7m

Convert meters to nanometers:

4.50 x 10-7m x 1nm/1 x 10-9m = 450nm

For future reference write the frequency like this, 6.67 x 1014 or 6.67e14.

Answer 5

Wavelength = speed/frequency = 299,792,458/6.09 x 1012 = 0.0492 millimeter

Answer 6

If you divide the speed of light (300,000,000 m/s) by the frequency (in Hz), you get the wavelength (in meters). Multiply this by 109 to convert to nm.

Answer 7

467 nm
