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:
Waves always carry energy.
The correct answer is: I and III
- Mechanical waves always transfer energy from one place to another.
- They don't carry matter.
- Therefore, statement II is correct but I and III are incorrect.
- So, the correct option is d.
