Best Answer

Using the formula:


where c is the speed of light in m.s-1;

λ is the wavelength in metres;

f is the frequency in Hz

We know that the speed of light is 3.0 x 108m.s-1 and the frequency is 4.6 x 1014Hz.



λ=(3.0 x 108)/(4.6 x 1014)

λ≈6.52 x 10-7m

What is the wavelength of a light of frequency 4.47 times 10 14 Hz?


What is the frequency of light with a wavelength of 1.87 x 10-14?

Frequency = speed/wavelength = 3 x 108/1.87 x 10-14 = 1.6043 x 1022 Hz.Note:That's no light. That's well into the gamma rays.

What is the wavelength of a light of frequency (4.47)(10 exponent 14) Hz?

The wavelength is 678,68 nm.

What is the frequency of yellow light, which has a wavelength of 5.56 x 10^-7m?

5.40 x 10^14 Hz

If blue light has a frequency of 6.98 10 14 hertz what is the wavelength in nanometers?

Just divide the speed of light (in meters/second) by the frequency (in hertz) - that will give you the wavelength (in meters). You can then convert that to nm.

If a beam of light has a wavelength of 506 nanometers what is the frequency of the light and what color is the light?

5.68 X 10^14? Then, speed of light = frequency * wavelength so, 2.998 X 10^8 m/s/5.68 X 10^14 s^1 = 5.278 X 10^-7 meters, or, 527.8 nanometers That would be green, I think.

What is the frequency of green light which has the wavelength of 4.90x 10 -7m?

velocity = frequency x wavelength 3x10^8 = f x 4.90x10^-7 f = 6.12x10^14 Hz

What is the frequency of light with a wavelength of 6.14x10-7?

Frequency=velocity of light/wavelength We know that the velocity of light is 3x10^8m/s From your wavelength, I am assuming that the number is in meters Thus the frequency =(3x10^8)/(6.14x10^-7) frequency = 4.8859x10^14 Hz

What is the wavelength in nm of a light in a vacuum that has a frequency of 40 x 10 14 Hz?

Wavelength = (speed)/(frequency) = 299,792,458/4 x 1015 = 7.4948 x 10-8 meter = 74.95 nm (rounded)

What is the frequency of ultra-violet?

The wavelength of ultraviolet light is between 10 and 400 nanometers (nm).From the wavelength you can determine the frequency. If you divide the speed of light by the wavelength, you can calculate the frequency.The frequency range would be from 7.5 x 1014 Hz to 3 x 1016 Hz.

Which has higher frequency ultraviolet or infrared?

Infrared and Ultraviolet light fall just outside human vision. The frequency of infrared light is less than the frequency of visible red light. There are different definitions and classifications of infrared, but the frequency ranges from 3 x 10 11 Hz (300 Gigahertz or 1000 micrometer wavelength) to about 4.3 x 10 14 Hz (0.7 micrometer wavelength). Ultraviolet's frequency is greater than the frequency of Violet light. This can range from 7.5 x 10 14 Hz (400 nanometer wavelength) to 3.0 x 10 16 Hz (10 nanometer wavelength). See related links.

What is the frequency of light that has a wavelength of 4.25 x 10-8 meters meters?

speed of light = wavelength(m) X frequency (^-s) Speed of light in a vacuum is 3.0 x 10^-8 ms^-1 Wavelength = 5.23 x 10^-7 m Hence frequency(^-s) = speed of Light (ms^-1) / wavelength (m) Hence frequency = 3.0 x 10^8 ms^-1 / 5.23 x 10^-7 m frequency (^s-1) = 5.74 x10^(14) (^s-1) NB This unit is naned Hertz (Hz) Hence frequency = 5.74 x 10^(14) Hz.
