The number of wave made by electron in one complete revolution in third Bohr's orbit are `:`

Options

A. nine
B. zero
C. six
D. three

Explanation

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

### Step 1: Understand the Bohr Model
The Bohr model states that electrons move in specific orbits around the nucleus, and these orbits correspond to certain energy levels. The angular momentum of an electron in the nth orbit is quantized and given by the formula:
\[ L = n \frac{h}{2\pi} \]
where \( L \) is the angular momentum, \( n \) is the principal quantum number, and \( h \) is Planck's constant.

### Step 2: Apply the De Broglie Hypothesis
