Question

Calculate the frequency and energy of a photon whose wavelength is having 6200 A⁰​

Answer 1

Answer

Frequency v=cλ

Substituting c=3×108ms−1,λ=6000Å=6000×10−10m, we get

v=3×108ms−16000×10−10m=5×104s−1

(ii) Energy of the photon E = hv

Substituting h=6.625×10−34Js,v=5×1014s−1, we get

E=6.625×10−34Js×5×1014s−1=3.3125×10−19Jwer:
