Question

The frequency of a note with a high pitch is greater than the frequency of a note with a low pitch. Which statement about the note with high pitch is not correct?

• A. Both I and II
• B. Both III and IV
• C. I, II and IV
• D. I, III and IV

Answer 1

The correct option is D

I, III and IV

An explanation of the correct option

D: I, III, and IV

Pitch: It is the characteristic of sound by which we can differentiate between different sounds of the same loudness. It is the characteristic of the source.

1. High pitch sound refers to more compression and rarefaction.
2. That means the higher the pitch higher the frequency.
3. From the equation$u=v\lambda$, we can say that the higher frequency is lower by wavelength.
4. The speed of the sound waves depends upon the propagating medium and hence it cannot be predicted from the pitch of the sound waves.

Thus, statements I, III, and IV are incorrect about notes with a high pitch.
