MCQ
How many times does the electron go round the first Bohr orbit in a second?
- A$6.57 \times 10^5$
- B$6.57 \times 10^{10}$
- C$6.57 \times 10^{13}$
- ✓$6.57 \times 10^{15}$
✓

$T_0$ in ground state of hydrogen is $=1.51 \times 10^{-16} \,s$
Number of revolution $=(f)=\frac{1}{T_0}=\frac{1}{1.5 \times 10^{-16}}=6.57 \times 10^{15}$
