QAIPM-2011-Ph-1886: NEET 2011 Physics - Class 11 AIPM-2011-Ph-1886 Solution: Two waves are represented by the equations \(y_1 = a ( t + kx + …

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 1.0 radian 1.25 radian 1.57 radian 0.57 radian

Multiple Choice Options

  • A [L1/2T−1/2]\left[ {{L^{1/2}}{T^{ - 1/2}}} \right] [ L 1/2 T _ 1/2 ]
  • B [L−1T]\left[ {{L^{ - 1}}T} \right] [ L _ 1 T ]
  • C [LT−1]\left[ {L{T^{ - 1}}} \right] [ L T _ 1 ]
  • D [L1/2T1/2]\left[ {{L^{1/2}}{T^{1/2}}} \right] [ L 1/2 T 1/2 ]

Step-by-Step Verified Solution

( _ 0 _ 0 ) _ 1 / 2 = 1 _ 0 _ 0 = Speed of light in vacuum = c So the dimension of ( _ 0 _ 0 ) _ 1 / 2 = [c] =[LT -1 ]
