Question

Sound can be passed through

• A. a particle moving from one place to another
• B. a particle moving about its fixed position, and influencing the particle next to it to do the same, and passing the trend to subsequent particles.
• C. Both A and B
• D. None of the above

Answer 1

The correct option is B

a particle moving about its fixed position, and influencing the particle next to it to do the same, and passing the trend to subsequent particles.

Sound can be passed through particles, where the particles don't move from one place to another. Instead. it just moves about its position, and influences the next particle to move as it does. This pass on of information from one particle to another, without the particle actually getting displaced from its fixed position, is generally referred to as a wave.
