1.	Two waves of the same frequency and intensity superimpose with each other in opposite phases . Then after superposition the ………….. .
Answer» INTENSITY increases to four times intensity increase to TWO times frequency increases to four times NONE of the above Solution :Since the waves are in OPPOSITE phases, the resultant intensity will be zero. The frequc remains the same. So, the correct CHOICE is (d).
