2 : 1

6 years ago


Answers : (1)


time period =T=2pir/v                       ( r is radius of orbit,v is velocity of elctron)


v is inversly proportional to n

r is directly proportional to n2

 so time period (T) is directly proportionla to n3 ....

  for  1 state n =1  , for first exited state n=2

    T1/T2= (n1/n2)3

      T1/T2= 1/8     

first option is correct
