**Identify the period. Do not sketch the graph.**

\[ y = \sin \left(\frac{1}{10} x\right) \]

---

### Explanation:

This prompt asks students to identify the period of the sine function \( y = \sin \left(\frac{1}{10} x\right) \).

#### Understanding the Period of a Sine Function:
- The standard sine function \( y = \sin(x) \) has a period of \( 2\pi \).
- When the function is modified to \( y = \sin(bx) \), the period is adjusted by the factor \( b \), and becomes \( \frac{2\pi}{|b|} \).

#### Calculation:
- In the given function, \( b = \frac{1}{10} \).
- Therefore, the period of \( y = \sin \left(\frac{1}{10} x\right) \) is calculated as:

\[
\frac{2\pi}{\left|\frac{1}{10}\right|} = 20\pi
\]

Thus, the period of the function \( y = \sin \left(\frac{1}{10} x\right) \) is \( 20\pi \).
