Question
Consider the following statements and select the incorrect statement(s) from the following.
I. Mechanical waves transfer energy and matter both from one point to another.
II. Mechanical waves transfer only energy from one point to another.
III. Mechanical waves transfer only matter from one point to another.
- I only
- II only
- I, II, and III
- I and III
Hint:
Mechanical waves transfer only energy as they travel
The correct answer is: I and III
Since mechanical waves move due to motion of particles hence they travel only energy and not matter
