QAIPM-2011-Ph-1887: NEET 2011 Physics - Class 11 AIPM-2011-Ph-1887 Solution: Two waves are represented by the equations \(y_1=a (…

Two waves are represented by the equations y1=asin⁡(ωt+kx+0.57)y_1=a\sin(\omega t+kx+0.57) m and y2=acos⁡(ωt+kx)y_2=a\cos(\omega t+kx) m, where x is in meter and t in sec. The phase difference between them is

Multiple Choice Options

  • A 1.0 radian
  • B 1.25 radian
  • C 1.57 radian
  • D 0.57 radian

Step-by-Step Verified Solution

Here, y 1 = a sin ( _ t + kx + 0.57) and y 2 = a cos ( _ t + kx) = a sin _ [ � 2 + ( _ t + k x ) ] Phase difference, _ _ = _ 2 _ _ 1 = � 2 _ 0.57 = 3.14 2 _ 0.57 = 1.57 � 0.57 = 1 radian
