Edexcel A-Level Physics AS 2.3.35 Longitudinal Waves Questions question 1

[Maximum number: 5]

The photograph shows a musical instrument called a violin.

Figure for Question Edexcel A-Level Physics AS 2.3.35 Longitudinal Waves Questions question 1 — Edexcel A-Level Physics AS

The violin has four strings. Each string is held in a fixed position by a peg and at the bridge.

When a string is plucked, a stationary wave forms on the string.

The stationary wave on the string causes sound waves to be transmitted through the air.

Describe the similarities and differences between the stationary wave on the string and the sound waves transmitted through the air.
