Find out the number of waves made by a bohr electron is one complete revolution in its third orbit

Explanation

To find the number of waves made by a Bohr electron in one complete revolution in its third orbit, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Bohr's Model**: According to Bohr's model of the atom, electrons can only occupy certain allowed orbits where their angular momentum is quantized. The angular momentum (L) of an electron in the nth orbit is given by:
\[ L = n \frac{h}{2\pi} \]
