Intensity equation light
NettetThe intensity of the light can be obtained using the relation I = 1 2 c ε 0 E 2 from Electromagnetic Waves. The intensity of the maximum is then I 0 = 1 2 c ε 0 ( N Δ E 0) 2 = 1 2 μ 0 c ( N Δ E 0) 2, where ε 0 = 1 / μ 0 c 2. The phasor diagrams for the first two zeros of the diffraction pattern are shown in parts (b) and (d) of the figure. NettetSo the difference in energy ( ΔE) between any two orbits or energy levels is given by ΔE = En1 − En2 where n1 is the final orbit and n2 the initial orbit. Substituting from Bohr’s equation (Equation 6.3.3) for each energy value gives. ΔE = Efinal − Einitial = − ℜhc n2 2 − ( − ℜhc n2 1) = − ℜhc( 1 n2 2 − 1 n2 1)
