Question

2. The frequency of strong yellow line in the spectrum of sodium is 5.09 x 1014s-1. Calculate the wavelength of the light in nanometers.

Answer 1

Answer:

c=λv

λ=vc

=5.09×1014sec−13×108ms−1

=5.09×10−7

=589×10−9

Answer 2

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
