What is meant by cyclotron frequency?

Explanation

**Step-by-Step Solution:**

1. **Definition of Cyclotron Frequency**: Cyclotron frequency refers to the frequency at which a charged particle orbits in a magnetic field. It is a measure of how many times the particle completes a circular path due to the influence of the magnetic field.

2. **Formula for Cyclotron Frequency**: The cyclotron frequency (often denoted by \( f_c \)) can be mathematically expressed using the formula:
\[ f_c = \frac{qB}{2\pi m} \]
