Final answer:
The frequency of a violin string that is 40 cm long is 5 Hz. This is deduced from the inverse proportionality between the length of the string and its frequency.
Explanation:
The length of a violin string and the frequency of its vibrations vary indirectly. That means if one variable increases, the other variable decreases, and vice versa. They are inversely proportional.
If the length is 50 cm and the frequency is 2 Hz, we can establish an equation 50 * 2 = k, where k is the constant of variation.
To find the frequency of a string that is 40 cm long, we substitute into the equation: 40 * f = k. Thus, the frequency ('f') will be 5 Hz (since k = 100).
