When two or more waves overlap at the same time the resultant wave will be the sum of individual waves. The principle is known as
Correct answer: D. Superposition.
- A. Reflection.
- B. Ultrasonic.
- C. Supersonic.
- D. Superposition.
Explanation
The correct answer is superposition. The principle of superposition describes how when two or more waves overlap, their individual displacements are added together to form a new wave. This concept applies to all types of waves, including sound and light. The other options do not relate to the concept of wave interaction: Reflection involves waves bouncing off surfaces, ultrasonic concerns high-frequency sound waves, and supersonic refers to speeds exceeding the speed of sound.

About Superposition and Interference
Superposition states that overlapping waves produce a resultant displacement equal to the algebraic sum of their individual displacements. Interference covers constructive and destructive interference, phase difference, path difference, coherent sources, and conditions for maxima and minima. It differs from diffraction, which involves spreading around openings or obstacles.
