Two sound waves P and Q are drawn on separate but identically scaled distance–amplitude graphs. In wave P, the distance between successive compressions is 0.60m, whereas in wave Q it is 0.40m. Both waves travel through the same medium. Which statement about their pitch is correct?
a) Wave P has a higher pitch than wave Q
b) Both waves have the same pitch
c) Wave Q has a higher pitch than wave P
d) Pitch comparison is not possible with the given data
