The radii of two Bohr's orbits of hydrogen atom are in the ratio of `4:9` . Which of the following value of energy difference is not possible between the two orbits? [I.E . = 13.6 eV]

A

1.9 eV

B

0.472 eV

C

0.66 eV

D

0.21 eV

Text Solution

Verified by Experts

The correct Answer is:
3
`(r_(1))/(r_(2))=(n_(1)^(2))/(n_(2)^(2))=4/9 rArr (n_(1))/(n_(2)) =2/3`
