Calculate the frequency of yellow light of wavelength 550 nm. The speed of light is \(3\times {{10}^{8}}m{{s}^{-1}}\)

Given,

550 nm is the wavelength\(=550\times {{10}^{-9}}m\)

\(c=3\times {{10}^{8}}m/s\) is the speed of light.

We are aware of this.

Frequency = Light Speed / Wavelength

Therefore,

Frequency of yellow light of wavelength \(=\frac{3\times {{10}^{8}}}{550\times {{10}^{-9}}}\)

\(=5.4\times {{10}^{14}}Hz\)
