Consider the following statements :1. A flute of smaller length produces waves of lower frequency.2. Sound travels in rocks in the form of longitudinal elastic waves only.Which of the statements given above is/are correct?
✓ Correct answer: d) Neither 1 nor 2
ExplanationStatement 1 is incorrect: The frequency of sound produced by a flute is inversely proportional to its length.A shorter flute produces sound waves of higher frequency (higher pitch), while a longer flute produces sound waves of lower frequency (lower pitch).Statement 2 is incorrect: Sound (or seismic waves) in rocks travels in both longitudinal (P-waves) and transverse (S-waves) forms.Longitudinal waves compress and expand the material, while transverse waves move the material perpendicular to the direction of propagation of the wave.256
