Calculate the radius of `1^(st), 2^(nd),3^(rd),4^(th)` Bohr's Orbit of hydrogen.

Explanation

To calculate the radius of the first four Bohr orbits of hydrogen, we can use the formula for the radius of the nth Bohr orbit:

\[ r_n = \frac{0.529 \, \text{Å} \cdot n^2}{Z} \]

Where:
- \( r_n \) is the radius of the nth orbit,
- \( n \) is the principal quantum number (1 for the first orbit, 2 for the second, etc.),
- \( Z \) is the atomic number (for hydrogen, \( Z = 1 \)).
