The wavelength of yellow color in a vacuum is 0.589 microns. What is the vibration frequency.

It is known that the speed of propagation of light in vacuum c ≈ 3 * 108 (m / s).

Between the speed of propagation of light in vacuum, the frequency of light (υ) and its wavelength (λ) there is a relationship, which is described by the formula:

c = λ * υ.

Let us determine the vibration frequency from this formula:

υ = c / λ.

Let us express the wavelength in SI units:

λ = 0.589 (μm) = 0.589 * 10 ^ -6 (m).

Let’s put the obtained numerical values into the last formula:

υ = s / λ = 3 * 10 ^ 8 / 0.589 * 10 ^ -6 = 1.767 * 10 ^ 14 (Hz)

Answer: υ = 1.767 * 10 ^ 14 (Hz).
