**Question 4:**

A sine wave has a frequency of 50 kHz. How many cycles does it complete in 10 ms?

---

**Solution Explanation:**

To find the number of cycles a sine wave completes, use the formula:

\[ \text{Number of Cycles} = \text{Frequency} \times \text{Time} \]

Given:
- Frequency = 50 kHz = 50,000 Hz
- Time = 10 ms = 0.01 seconds

Substitute the values into the formula:

\[ \text{Number of Cycles} = 50,000 \, \text{Hz} \times 0.01 \, \text{s} = 500 \]

Thus, the sine wave completes 500 cycles in 10 ms.
