  • also you can get by finding the energy difference that is =n=1=-13.6ev ,n=4=0.85ev ,the difference is 12.75ev convert to joules wihich is multiply by 1.6*10^-19=2.04*10^-18j, using formula of finding lambda= (6.63*10^-34j*3.0*10^8)/(2.04*10^-18j)=9.75*10^-8m

  • "Calculation Mistake"Energy in above Equation = 12.75 ev = 2.04*10^-18 J, Because it jumping from N=1 to N=4, Hence wavelength = h*c / 2.04*10^-18 J =9.744 * 10^-8 meter.
