Question
A sodium street light gives off yellow light that has a wavelength of 600 nm. Then
(For energy of a photon take E =
)
(For energy of a photon take E =
)Options
A.frequency of this light is 7 × 1014 s-1
B.frequency of this light is 5 × 1014 s-1
C.wavenumber of the light is 3 × 106 s-1
D.energy of the photon is approximately 2.07 eV
= 5 × 1014 sec-1 
= 2.07 eV.More Atomic Structure Questions
