standing wave on a 1.64 m long horizontal string has two nodes – i.e., locations on the string (excluding the two ends) that remain stationary as the string vibrates in place – when the string vibrates at 120 Hz. The maximum swing of the string (top to bottom) at the centre of each loop is 8.0 cm. a) What is the function describing the standing wave? b) What are the functions describing the two equal-amplitude waves
Interference of sound
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.
A standing wave on a 1.64 m long horizontal string has two nodes – i.e., locations on the
string (excluding the two ends) that remain stationary as the string vibrates in place –
when the string vibrates at 120 Hz. The maximum swing of the string (top to bottom) at
the centre of each loop is 8.0 cm.
a) What is the function describing the standing wave?
b) What are the functions describing the two equal-amplitude waves travelling in op-
posite directions that make up the standing wave?
