The G string on a violin has a fundamental frequency of 196 Hz. It is 30.0 cm long. While this string is sounding, a nearby violinist effectively shortens (by sliding her finger down the string) the G string on her identical violin until a beat frequency of 2 Hz is heard between the two strings. When this occurs, how far down the string did she slide her finger? Assume that the velocity of waves on the violin string does not change when you press on the string with your finger.

Seiche
A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water including bays and lakes. A seizure can happen in any enclosed or semi-enclosed body of water.
