Answer 2

We know that Frequency - Wavelength of a Light are Related by :

• c = νλ

• c is the Velocity of the light in Vacuum which is 3 × 10⁸ m/s

• ν is the Frequency of the Light

• λ is the Wavelength of the Light

Given the Frequency of the yellow line is 5.09 × 10¹⁴ s⁻¹

⇒ 3 × 10⁸ = 5.09 × 10¹⁴ × λ

$\implies \lambda = \frac{3\times10^8}{5.09\times10^1^4}$

⇒ λ = 5.89 × 10⁻⁷ meter

Wavelength of the Light = 5.89 × 10⁻⁷ meter
