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
