What is the principle of superposition in wave theory?.
- A.The total displacement at any point is the sum of the displacements from individual waves.
- B.Waves can only exist in isolation without interaction.
- C.The amplitude of a wave is determined by its frequency.
- D.Waves cannot interfere with each other.
Model answer
What a good answer should say
- The total displacement at any point is the sum of the displacements from individual waves.
Explanation
Why this works
The principle of superposition states that when two or more waves overlap, the resultant displacement at any point is the sum of the individual displacements of the waves. This principle is fundamental in understanding wave interactions.
