1.	If Energy = 4.5 KJ; calculate the wavelength.(a) 4.42 x 10^-29 m(b) 4.42 x 10^-39 m(c) 4.42 x 10^-25 m(d) 4.42 x 10^-22 mThis question was addressed to me by my school teacher while I was bunking the class.I need to ask this question from Developments Leading to the Bohr’s Model of Atom in section Structure of Atom of Chemistry – Class 11
Answer» Right choice is (a) 4.42 x 10^-29 m Explanation: We know E = hv through Planck’s QUANTUM Theory, where E is ENERGY, h is Planck’s CONSTANT and V is the frequency. 4.5 KJ = (6.626×10^–34 Js)(3 x 10^8m/s)/(wavelength). wavelength = 4.42 x 10^-29 m.
