Let T1 and T2 be the energy of an electron in the first and second excited states of hydrogen atom, respectively. According to the Bohr's model of an atom, the ratio T1:T2 is
  1. 4:1
  2. 4:9
  3. 9:4
  4. 1:4

Solution

Given T1⇒ Energy of 1st excited state

For T1⇒n=2

For T2⇒n=3

We know, Energy ∝1n2

∴ T1T2=3222=94
