Frequency of a light with a wavelength of 580nm?

Answer 1

The color of the wavelength lambda = 686.2 nanometers is "deep red". The wavelength lambda = 685 nanometers equals the frequency f = 436,887,872,340,425 Hz. 1 nanometer = 1×10−9 meter. 686.2 nm = 0.0000006862 meters. Scroll down to related links and look at "Radio and light waves in a vacuum".

Answer 2

v=fλ

Visible light is an electromagnetic wave. All electromagnetic waves travel at 3.0x108 m s-1 in a vacuum. Since the question doesn't supply additional info I'm assuming the medium is a vacuum.

Hence, v=3.0x108 m s-1 and λ=486x10-9 m.

Therefore, f=v/λ = 6.17x1014 Hz

Answer 3

Frequency = (speed of light) / (wavelength) Frequency = (300,000,000) / (5 x 10-7) = 6 x 1014 Hz = 600,000 GHz

Answer 4

c = 3 * 10^8 lambda = 580 * 10^-9


c = lamda * frequency


(3*10^8)/(580*10^-9) = 5.17241379 × 1014 m/s

Answer 5

f = c / (wavelength). For light, let c = 3 x 108 m/s; f = (3 x 108 m/s) / (5 x 10-7 m) = 0.6 x 1015 s-1 = 600 teraHertz
