Interference and refraction

Diagram below shows the interference pattern of water waves.
Rajah dibawah menunjukkan corak interferen gelombang air.



What happens to the separation between  two  consecutive nodal lines, x,  if the
depth  of  water in the ripple tank is increased?
 Apakah yang akan berlaku kepada jarak pemisahan 2 garisan nodal berturutan, x,  jika 
kedalaman air dalam  tangki riak meningkat? 

A.  Unchanged / Tidak berubah  
B.  Increase / Bertambah 
C.  Decrease / Berkurang
