Answer 1

which transition will emit light with the Shortest wavelength ? warelength (d) & I a frequencylf) And frequency (f) &. Energy So fore shortest wavelength, the emitted light will have maximum energy from the given possible freansitions. when transitions occurs from here to lower states light is emitted. In cose oj n » 63 -13.2/ 2-1316 ( 4 146 ] = 0.5ner In case of B → E= -13. 3.0 [s 47-0987ev In case of c E = -31687 5-13,6 - 7 -1.13 ex In case of a → E = -3.6 / 1 / 2 - 27 = -13.6 / 's $7>2.85ber E F G and H will not emit light as ni 7 DE So in case of D, eneagy reeleosed is maximum So the corresponding light will have shortest wavelength. 4

So the atom gain the most energy in Cose of G. As energy gained by atom is directly proportional to fr - t. ), which was found out to be highest in case G. proportional to ng nih, Core G.

tream For which transition will the atom gain the most energy! Atom will gain energy il transition occurs a lower to higher state. so. E, F, G and it will only gain energy as ni ynf.
