{'waves': [0, 0, 3, 0], 'longitudinal elastic waves': [0, 0, 1, 0], 'flute': [0, 1, 1, 0], 'sound travels': [0, 0, 1, 0], 'lower frequency': [0, 0, 2, 0], 'rocks': [9, 0, 3, 15]}

Both statements given are correct.

  1. A flute of smaller length produces waves of lower frequency: This is because the frequency of a sound wave is inversely proportional to the length of the medium through which it travels. Therefore, a flute of smaller length will produce waves of lower frequency.

  2. Sound travels in rocks in the form of longitudinal elastic waves only: This is because rocks are solids and can transmit only longitudinal waves, also known as compressional waves. Unlike solids, liquids and gases can also transmit transverse waves.
