Let's determine the type of waves that interact with each other to make nodes and antinodes when the string in a violin vibrates.
Sanding waves can be said to be a combination of two waves which move in opposite direction. Each of the waves have the same frequency and amplitude.
These waves interact with each other.
They are also called stationary waves.
They make nodes and antinodes which are found where the wave forms.
Therefore, when the string in a violin vibrates, the waves which interact with each other to form nodes and antinodes can be classified as standing waves.
ANSWER:
Standing waves.
