Question

14) It
es energy
If the energy difference between the ground state
and excited state of an atom is 4.4 x 10-19 J. The
wavelength of photon required to produce this
transition is
(1) 4.5 x 10-7 m (2) 4.5 x 10-7 nm
(3) 4.5 x 10-7 Å
(4) 4.5 x 10-7 cm
ans:wavelength=hc/v
wavelength=(6.626×10^-34j/s×3×10^8 m/s) ÷4.4 ×10^-19j
wavelength=4.5×10^-26×10^19
wavelength= 4.5 ×10^-7m
