Answer:
Wavelength = 580 nm
C= Wavelength × Frequency = 3×10^8 m/s
Frequency = C/Wavelength = 3×10^8/580×10^-9 s^-1
= 3×10^8/58×10^-8 s^-1
=0.0517241379 × 10^16 s^-1
= 517,241,379 × 10^6 s^-1
Wave Number = 1/ Wavelength
= 1/ 580 ×10^-9 m^-1
=1/58 × 10^-8 m^-1
=0.0172413793 × 10^8 m^-1

Answer:
frequency=
wavenumber=
Explanation:
wavelength of sodium lamp(λ)=580nm=
as we know the equation, c = λf
and the velocity of light(c) = m/s
frequency(f)=c/λ
f=()/580=
and wavenumber is nothing but the reciprocal of λ
wavenumber =1/λ =
