Question

Calculate the wavelength,wave number and freqency of photon having energy equal to three electron volt. (h=6.6*10^-27erg . note = 1eV =1.6*10^-19J or 1.6*10^-12erg​

Answer 1

Answer:

ANSWER

We know that,

E=h⋅v

v=hE     (1eV=1.602×10−12erg)

   =6.62×10−273×(1.602×10−12)

   =7.26×1014s−1

   =7.26×1014Hz

λ=vc=7.26×10143×1010=4.132×10−5cm

vˉ=λ1=4.132×10−51=2.42×104cm−1.
