Answer:
To find the wavelength (\( \lambda \)), we can use the formula:
\[ \lambda = \frac{2L}{n} \]
Where:
- \( L \) is the length of the string.
- \( n \) is the number of antinodes.
Given:
- \( L = 296 \) cm = \( 2.96 \) m (converted to meters).
- \( n = 2 \) (since the string has two antinodes).
Substitute the values into the formula:
\[ \lambda = \frac{2 \times 2.96}{2} \]
\[ \lambda = 2.96 \]
So, the wavelength is \( \lambda = 2.96 \) meters.
