Question

the frequency of a strong yellow line in the spectrum of sodium is 5.09*10¹⁴ sec-1. calculate the wavelength of light in nm​

Answer 1

Answer:

589 nm

Explanation:

Given The frequency of a strong yellow line in the spectrum of sodium is 5.09*10¹⁴ sec-1. calculate the wavelength of light in nm

We know that

    frequency = speed of light / wavelength

     ν = c / λ

    λ = c / ν

       = 3 x 10^8 m / s / 5.09 x 10^14 s^-1

      = 0.589 x 10 ^-6 m

    λ = 589 nm

So the wavelength of light is 589 nm
