Question

list three reasons to support the idea that sound is a wave

Answer 1

Following are the three reasons to support the idea that sound is a wave:

1. A sound wave is a longitudinal wave that is produced due to the vibrating motion of particles. A sound wave contains peaks and troughs.

2. A sound wave undergoes constructive and destructive interference. It obeys the law of interference.

3. In a single frequency, sound waves produce sinusoidal shapes.

Answer 2

Following are the reasons that prove the fact that sound is a wave:

1. It has peaks and troughs.

2. It causes resonance.

3. They also undergo constructive and destructive interfaces.

Furthermore, they can create sinusoidal shapes, undergo the phenomena of reflection and refraction, and carry energy from one given place to another.
