If tension of a sire is increased to four times, how is the wave speed changed?

Explanation

To determine how the wave speed changes when the tension in a wire is increased to four times its original value, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Wave Speed Formula**: The speed of a wave (v) in a string or wire is given by the formula:
\[ v = \sqrt{\frac{T}{\mu}} \]
