Ratio of radii of second and first Bohr orbits of H atom is

Ratio of radii of second and first Bohr orbits of H atom is

Options

  1. A2
  2. B4
  3. C3
  4. D5

Correct answer

B. 4

Step-by-step solution

According to Bohr rule, r∝n2r \propto n^2 where rr is radii and nn is the number of orbit So, r1r2=(2)2(1)2=4\quad \frac{r_1}{r_2}=\frac{(2)^2}{(1)^2}=4 Hence, ratio of radii is 4
