\phi

. Both waves have the same intensity. Match the following two columns.

Column I	Column II
(a) If $\phi=60^\circ$	(p) Resultant intensity becomes four times
(b) If $\phi=90^\circ$	(q) Resultant intensity becomes two times
(c) If $\phi=0^\circ$	(r) Resultant intensity remains unchanged
(d) If $\phi=120^\circ$	(s) Resultant intensity becomes three times
