Dear Student,

v- = 500 cm-11
 λ=1v-or, λ=1500= 0
2×10-2 cm-1=0 2 m2
 v-=vcor, v=v-×c        = 500 ×3×1010        = 1
5×1011 s-13  Time period,T=1vor, T=11
5×1011=0 666×10-11 s=6 66×10-12 s4
 E= hv        = 6
626×10-34×1
5×1011        =9
939×10-23 J5  1 kcal=4
18×103 Jor, 1 J=14
18×103kcalTherefore, 9 939×0-23 J=14
18×103×9 939×10-23=2 37×10-26 kcal

the wave number of a radiation is 500 cm-1 . find out its wavelength frequency time period energy in terms of joule per photon energy in terms of kcal per mole of photon
