QAIPM-2000-Ph-3016: NEET 2000 Physics - Class 11 AIPM-2000-Ph-3016 Solution: The equations of two waves acting in perpendicular directions…

The equations of two waves acting in perpendicular directions are given as x=acos⁡(ωt+α)x=a\cos(\omega t+\alpha) and y=acos⁡(ωt+β)y=a\cos(\omega t+\beta), where δ=α+π2\delta=\alpha+\frac{\pi}{2}, the resultant wave represents

  • A a parabola
  • B a circle
  • C an ellipse
  • D a straight line

Step-by-Step Verified Solution

Given : x = acos( _ t + _ ) and y = acos( _ t + _ )     ...(i) where, _ = _ + � / 2 _ x = a c o s ( _ t + _ + � / 2 ) = �asin( _ t + _ ) ...(ii) Given the two waves are acting in perpendicular direction with the same frequency and phase difference � /2. From equations (i) and (ii), x 2 + y 2 = a 2 which represents the equation of a circle.
