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:
It can transfer only energy.
The correct answer is: I and III
- Mechanical waves don't transfer matter, it can only transfer energy from one point to another.
- Therefore, the correct statement is II and incorrect statement is I,III.
- So, the correct option is d.
